Haskel seems awesome.

Absolutely nothing in common in php

With Haskell you barely have control what are doing. With C++ you even deallocate memory by yourself

@irene some tang said so

Lol. Try it.

I actually like the reply to it way more than the tweet itself

I like recursive functions as much as the next guy but fuck Haskell. I need my programming languages to have variables and for loops.

"faster than C++" (gif works for java Haskell python ...)

📌

@irene pretty much #lowlevelmasterrace

@irene so i heard but I've never actually seen it or used it I'd love to learn it just for fun but i already have shit tons of things i need to learn

@irene Looks likes it is just a quote for haskell people to say, even mentioned in haskell wiki. https://en.m.wikiquote.org/wiki/...

@irene by being lazy and not doing things for needed to be done

@vkubre ya, that feeling of being in control is warm and fuzzy, except you need decades to be actually in control with c++

@illusion466 why do you say so?

King Heroin

Functional programming elitists..........

@Mayhem93 how having a brain is an elite thing?

@irene what do you mean by cleverness exactly?

@idomurrcurr touting that your language is the best and the rest is shit has nothing to do with having a brain. In fact, it has everything to do with begin an elitist jerk with the vision of a horse who can't see past their farmland. Tell them about php and they will slap you with their hooves.

@irene it's not *just* runtime check, the unused code paths are eliminated by a compiler by trivial graph traversal. Which can't be trivial in imperative languages, 'cause all the code being impure by default.

@Mayhem93 why, not all of them are shit. Just these mainstream ones I've worked with for last fucking decade and have so fed up with them and computer abolitionist assholes defending the right to assign a human to the job computers were fucking invented for over and over again. /rant

@irene still enough for 99.99% applications

@irene and I'm barely scratching the surface. Just consider this - functional programming is *very* different, so any assumptions you may have from previous experience are likely incorrect. Mine, for one, were (mostly because being self-taught).

@irene low-level - probably, high-level - probably not.

@irene It is perfectly possible to program functionally on an imperative language. It's just that languages like haskell force you to write that way. It's not like functional is something unnatural that needs to be converted with overhead. And you can override laziness if really necessary.

Be like Haskell

@irene well the business logic is high-level, and c++, among many other, actually lacks sum types (no, std::optional is months old and probably won't make 90% of existing projects; no, std::variant might or might not land C++ 2020) which forces you emulate them with trees of ifs and cases carefully handling errors with exceptions when you actually need goto, or some AbstractVisitorFactory nonsense you'll forget next day (not sure which is worse).

Consider this instead:

Designing with types: Making illegal states unrepresentable

Haskell, in principle, can compile to faster code than C for certain examples.

It uses an intermediate called C-- before compiling, and because Haskell has such a thorough type system, and uses lazy evaluation, GHC can optimize a lot more than GCC.

Strict types and laziness are benefits for the compiler, and they are independent from Haskell being a functional language.

Being a Functional language tends to slow things down: You often use several "loops" (tailrecursive functions like map, zip, filter) instead of doing all operations in one single for loop.

However, that is a tradeoff: such highly abstract building blocks make code safe, concise and modular.

Take point 1 and 2, and you end up with something faster than Java, safer than C and more concise than Python.

In practice, that is where Haskell shines: Ultra correct software for banks, laboratories and engineers, with a package ecosystem highly geared towards abstract math and simulations.

@bittersweet thank you.

@localghost127 thank you very much :P

@Krokoklemme really wasn't expecting this 😂😂

@bittersweet excellent detailed reply! I was about to barge in saying about the same things but not as neatly phrased.

There is also something called Cloud Haskell now which aims to capture some of the backend development. Although I think it's (and will stay) experimental

There's a write-up from a yesterday's keynote talk at fby.by by Michael Snoyman explaining why Haskell actually _is_ awesome - https://snoyman.com/blog/2017/...

$ docker run -it --rm haskell:8
Just one Gig ! 😎

@spacem Haskell has variables and there is a package with loops.

Good for you! What is it?

Care to name a few?

That's odd, my experience is quite opposite.
