I think it'd be great if +=, ~=, +&=, ++, etc, could all assume $_ on
their LHS when there is no obvious operand.
This clashes with &prefix:<=>, but that's nothing a space cannot fix.
Same for lvalue subs called x or xx (or X or XX).
my $subject = "foo foo foo";
given ($subject) {
s/foo/bar/; # "bar foo foo"
++; # "bar foo fop"
x= 2; # "bar foo fopbar foo fop"
~= "!"; # "bar foo fopbar foo fop!"
}
Especially bare ++ would be useful, I think.
