I just want to briefly register a formal complaint that I do not like
this, and I suspect I'm not the only one. I just think many have stopped
trying to fight it out of exhaustion.
I don't like ~ for binary concat. For one thing, it means that the
equivalent of .= is now:
$a ~= $b
Does anyone else see a problem with =~ ? Plus, it makes the
pre-plus-concat that many desire impossible, since =~ is taken.
Second, even if ~ *is* used for concat, then I *still* don't think that
~ should be changed from unary negation. There's no reason for it. Every
other major modern language I can think of uses ~ for unary negation. An
operator can change its meaning based on context, just consider <<.
In summary:
1. I don't like ~ for concat
2. But if it does become concat, then we still shouldn't
change ~'s current unary meaning
Thanks for listening.
