Re: string.gsub and its need for variables..

[Asko Kauppi <asko.kauppi@...>]

I wasn't referring so much to 'string.gsub' but the fact that sometimes 
a functions return values are passed all, sometimes only one.  I do 
_know_ how it goes, and so forth, but it certainly is a trap for 
newcomers.

Should we do a "Common Lua Pitfalls" :) list somewhere (the wiki?).  
That could help, since I don't have a better overall solution to 
recommend either.
