For that particular case, you don't need either the -> or the &{}:
sub x{ say "x got [ @_ ]"; };;
$h{x} = \&x;;
$href = \%h;;
$href->{x}('fred','bill');;
x got [ fred bill ]

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
