Most hated language features?

PL/SQL:
• it exists

XSLT:
• it also exists

PHP:
• it still exists.

VB:
• Significant parentheses: `subName` calls the subroutine, and `subName()` calls the subroutine and gets a return value. If you use the wrong invocation, it yells at you. Why!?
• For reasons unknown, you can only have `sleep` appear once per codebase. (So put it in a function!)

Ruby:
• It’s bloody easy to write code with absolute shit performance, and it kind of feels encouraged because of just how easy Ruby makes everything. Less critical thinking means worse performance, and Ruby’s blissful elegance encourages mental laziness.
• Minor: You cannot pass a hash as the first method parameter without enclosing it in parentheses, ex:`method({key: value})`. This is due to the ambiguous case between passing a hash argument and a (curly) block/proc (`method {|args| code}`). This could be remedied pretty easily with a little bit of look ahead.
• Minor: There is no `elsif` for `unless` (a negated if). Why? No reason given.

Python:
• no block endings, so nested code can be extremely difficult to follow.

Bash:
• The freaking syntax oh god why.

All languages:
• rand vs rand() vs Rand vs Rand() vs rnd vs RND vs random() vs random vs randInt() vs Math.random() vs Math.randInt() vs ...
