Wrong because it's inconsistent. Nothing else defaults to $?SELF.

Current spec.

Not special syntax, meaning you can no longer use these identifiers for
your own class. Bad style to use single-letter identifiers, but we know
what trouble $a and $b in Perl 5 cause, and the B:: namespace.
> ^
Introduces whitespace-asymmetry:
1+.foo
1+ ^foo # +^ is a bitop
> ->
Clashes with sub creating ->
my $method = "foo";
->$method;
Can be done with look-ahead, but this is to be avoided.
> _
Requires fundamental change in identifier naming rules. Means you're taking
away all of _foo, __foo, __foo__, etcetera, from user definition.

Not on any of the keyboards that I regularly use, and the
ascii-equivalent would be \w, which has the problems described above.

Very possible, but lacks mnemonic, while it does look like it has to do
with some mnemonic, because a character is repeated.
