Not to start a holywar, but to merely show the contrast opinion: I,
personally, would *not* be happy to see features 3, 4 and 6 in Lua.
I'm not discussing here why — pros and cons were discussed extensively
in the past.
Granted, if I see these features added in Lua, I would not be too
unhappy, and maybe would even use some of them from time to time. But
I would see inclusion of these features as an indication that
something is wrong with Lua team. :-) Anyway, definitely, features 3,
4 and 6 would not be pros for *me* when considering switch to 5.2.
I use LJ2 for features 1 and 2 (but then I'm not on embedded). And, as
I'm not on embedded and PPC Macs are all but gone, feature 5 is not
quite relevant for me as well.
So, strangely enough, none of features you request from 5.2 would sell
it to me. I'm not saying that there is something wrong with your point
of view or right with mine, mind you. That's just to illustrate that
language design is hard :-)
