I golfed some problematic code to the following :
> multi sub f(@p, Range $r? ) { say 1 }; multi sub f([], Range $r) {
> say 2 }; f([], 1..2);
2
> multi sub f(@p, Range $r?, Bool :$mod){ say 1 }; multi sub f([], Range $r) {
> say 2 }; f([], 1..2);
Ambiguous dispatch to multi 'f'. Ambiguous candidates had signatures:
:(@p, Range $r?, Bool :mod($mod))
:(Positional (), Range $r)
The first line behaves as intended.
Adding a named parameter makes the dispatch ambiguous.
The second function which was not a candidate seems to become a
candidate by adding
a named parameter.
