argcheck()

[Stijn]

After hurting my head on luaL_argcheck in the Lua manual, I found that this function is declared at the top of the file

Just one thing I don't understand, why do you start counting arguments at 2 ?
For example, if you do

oUF:RegisterStyle("abc","def")

you get

Bad argument #3 to 'RegisterStyle' (function, table expected, got string

while "def" is argument #2

oUF:RegisterStyle("abc","def")

Is syntactic sugar[1] for:

oUF.RegisterStyle(oUF, "abc", "def")

In stock Lua we can actually get information about which type you called through the debug library, but we don't have access to that in WoW.

[1] Slightly incorrect to actually call it syntactic sugar, as Lua actually has a optimization for that path.

Ok, now it makes sense. Thank you
