Rather than Perl-izing it, I would say: bringing it in line with most
of modern languages.
FWIW, Lua's solitary choice of ~= is a weird quirk.
Personally I'd prefer ¬= myself. Because ! to me means "send message" in a language I use that's far more modern than C or C++ or any of the other curly brace blight languages.
I cannot believe that people are calling syntax from a language created in the '60s (be very careful before trying to challenge me on this date!) "modern".
