Re: Excessive expressions in assignment (was: Garbage Collector)

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

I wouldn't mind such a warning (not an error, really?) at block read 
time. Also, it could possibly be switched off by some Lua configuration 
"flag" or something?

Where this would help is bringing new people to Lua and smoothening 
their way.

The multiple assigment notation itself is powerful & nice, though, and 
I'd hate to remove it altogether.
