It's not inconsistent. Just because your language can do assignment
doesn't mean it can do destructuring bind.
As it happens, Perl *can* do destructuring bind. You want parentheses
around the list though:
my ($str, $ref) = ('text', {a => 1, b => 2, c => 3});
say $ref->{b};
(Your line parses the hash reference in void context, as you'd see if
you're using warnings.)
