@C0D4 deep

@Demolishun i did search, infact its documentation is on the book im reading, i am just saying that lexical variables are fucking confusing and deserve a better explanation

@frogstair throw a bunch of letters and you have a bot, lemme try yibg

@frogstair "let me google that for you"

@frogstair 🤔 I get this result.

When a variable is lexically scoped, the system looks to where the function is defined to find the value for a free variable. When a variable is dynamically scoped, the system looks to where the function is called to find the value for the free variable.

Lexical variable: not in my scope, can't see shit. Did you not see the brackets on the way in?

@frogstair yeah i know what it is but lisp has a twist added to it which makes it confusing

@SortOfTested lexical variables are pretty simple in other languages but in common lisp oh boy did i suffer learning them

{ var this: Is = "one" }

Oh lisp then something like

(a [b] [var these are ones] c)

@yellow-dog i think the last example was (defparameter *fn* ( let ((a 1)) (lambda (x) (+ a x))))
and then (funcall *fn* 6)
which would i give 7
i understand what it does but im not really getting the meaning of it, a lexical variable is one binded with the function?

Sorry, this is clojure syntax, havent used lisp in a long time but they are fairly similar. Look up variable shadowing.

In this case, var1 is a lexical variable of the function scope and the universe scope, with function scope taking precedence.

So basicly lexical=local?

@Gregozor2121 yeah but in lisp theres 2 types of local lexicals and some other, lexicals have somekind of twist
