Yet.
+1.
I'm using functions as keys in reverse tables (see PiL for reference) to save functions' bindings to GUI controls in text files.

Don't listen to Karai17, he's being obtuse.

There's nothing inherently wrong in using tables or functions as keys. It's just a bit advanced, and it's preferable to learn the basics well first.
When I write def I mean function.

Yeah, sorry, I am just being silly. As kikito said, there is nothing inherently wrong with it, but it is a very advanced activity.

Never mind.
Actually functions as a tables' keys can be very useful:

Code: Select all

fn1 = function(x) print(x) end
fn2 = function(x) print("bar") end
t[fn1] = "foo"
t[fn2] = "foo"
for i, v in pairs(t) do i(v) end
(from http://stackoverflow.com/questions/1456 ... table-keys)

Not too difficult to use and can be very powerful imo.

Weird.
This code runs well. (t was undeclared, so I added t = {})
Looking at the 'for' cycle. v is undeclared, what is pairs?

UPD: Nevermind, found it out. http://www.lua.org/pil/4.3.5.html
