RE: Redefining locals

["Bilyk, Alex" <ABilyk@...>]

Some people (not me) now say 
	local _,_,x = <whatever>
all over their scripts and this relies on 
	local a, a
being valid in Lua... as odd as it is.

I wonder if this has been done intentionally or is it really unintended result of keeping things simple. I think the latter is the case and now a bunch ot people got dependent on it.

But who's really dependent on it? You can always achieve the same
result with extra scopes, can't you? It seems like a really strange
feature to me...
