Do you know what that would mean to all the existing codebase... ?
Every that uses the current form would have to change his software just
because of your personal taste?  You can't be serious?

Impractical and quite crazy to even suggest such a change.  If you dont
like _G etc. why don't you make a table for you that contains these
elements?  That would be easy enough.
