subroutine signatures
Declarative syntax to unwrap argument list into lexical variables.
"sub foo ($a,$b) {...}" checks number of arguments and puts the
arguments into lexical variables. Signatures are not equivalent to the
existing idiom of "sub foo { my($a,$b) = @_; ... }". Signatures are only
available by enabling a non-default feature, and generate warnings about
being experimental. The syntactic clash with prototypes is managed by
disabling the short prototype syntax when signatures are enabled.
