I intended to learn Lua, until I found out that variables are global by default, and you have to add a keyword to limit their scope to the current sub/method.

That's true in Perl too if you don't use strict. Well, so in Perl the alternative is lexical scope which, as I know from certain other *ahem*VB*ahem* experience, is much better than subroutine scope for most purposes.
