Now, I'll be the first to recognize that my latest message in this
list was kind of flamebait material, but honestly, I can't understand
the need to change the language.

This particular suggestion... sure you have to declare variables and
sometimes it bites you in the rear end, but the alternative seems so
much harder to understand.

I believe it's rare to find someone that learned Lua has his first
(programming) language so Lua is bound to have at least one missing
feature (there is a saying, at least here, about trying to please both
Greeks and Trojans...)

Lua has its scope and I believe that Roberto and Luiz have made it
clear that it's not about replacing Python/Ruby; frankly, that seems
to be the aim of all this suggestions.
