number of parameters of a function

[Edwin Eyan Moragas <haaktu@...>]

Hi all,

this may have been asked before but my search didn't
come up with something i need.

a little bit of meta programming. given a function, say:

local function foo(bar, baz)
-- whatever
end

how can i determine the number of parameters this function
needs?

TIA.
