Hi Egor,
sorry for sending this directly to you but I'm no longer subscribed to lua-l
and can't post it there.

Browsing through the pile-up of lua-l mails I found your article and just
want to let you know that, contrary to most of the negativ replies, I totally
agree with your proposal. So much that I once (in 2013, for Lua 5.2) even
did a patch that implements it ;-)
I had one difference though: the parser starts in regular lua mode and only
if it detects the first $-sign it switches to "explicit globals" mode for
that chunk. That way it was 100% backwards compatible.
Ciao, ET.
Thanks, Edgar.
I like it too - when a new feature is simultaneously useful and 100% backwards compatible.
So, you've made a patch for parsing $-globals 5 years ago?
Nice!
