Re: My wish list :) [RE: How can we make lua better?]

[John Belmonte <jvb@...>]

I'm not interested in taking sides on this, just plugging the lua-l 
archive :-).

After spending a while on this list, you notice that some issues come up 
repeatedly.  As Rici points out there are subtle issues with optimizing 
the "+=" expressions.  The Lua authors have already considered and 
commented on adding such expressions to Lua.  Just go to the lua-l 
archive and type += in the search box.

If you are trying to make a convincing argument to the list, it can't 
hurt to check the archives for past discussions.  It may save everyone 
some energy, or make your argument more effective.  (Dynamic module 
thread take note!)
