Re: loadstring to create a function with parameters

[Asko Kauppi <askok@...>]

If you need to get return values via loadstring, how about:

loadstring( "return "..funcName.."()" ) ()

..But I fail to see why you couldn't simply:

funcXY()

Functions don't have names in Lua; they are just values in variables.  
So you can toss them around as you would any value. Hope this helps?
