I don't think this isn't a bug. This is just how signature binding works:
my ($a,$b,$c) := [10,20,v => 30]
Too few positionals passed; expected 3 arguments but got 2
in block <unit> at -e line 1
It makes sense to me because otherwise what would this mean?
sub s(@($a,$b,:$c)) { .... }
Pair elements have to become bound to named parameters in the sub-signature.

Consider:
sub s(@ ($a, $b, $c)) {
note [$a,$b,$c].perl;
}
s([10,20,30]);
s([10,20,v=>30]); # dies
