are there any languages that i dont know of that allow you to "open-air" function calls (call functions without parenthesises)
ones i know allow you to do this
* ruby
* perl
@boots also BASICs sometimes have this to mimic the syntax of built-in functions, but most use some kinda "gosub", or dont have function abstraction at all
@boots ML languages like OCaml uses "open-air" function calls, and allow partial evaluation of function by not giving all arguments (returning a new function).
Forth is build around a stack and uses a postfix notation for function calls ("reverse polish" notation). As a consequence, it does not need parentheses.
Although lisp languages uses parentheses, they surround the function symbol and its arguments, resulting in something looking a bit like "open-air" calls.
@boots i guess theres the old python "print" but does that count
