Re: _ENV vs _G

[Axel Kittenberger <axkibe@...>]

For a programming language the more answers to questions in the style of "why is this done that way?" the proper answer starts with "this is best explained historically, first there was, then, etc. ..." the more awkward the language becomes as whole.

Ah, but that's not a correct substitution - _ENV starts out as _G, but
may change.  For the idiom where one's doing _G.print in a module with
new _ENV the fix would be the 'local _G = _ENV' at the top that was
suggested.

But really, why?  This mania for deprecation puzzles me.
