I haven't followed the entire thread in depth so I apologise if this was already answered, but I haven't noticed it being mentioned/clarified yet. Can you clarify in the following, is the arm comparing against match's default or the parameter's default? Or to put it another way, in the second call, If $arg is 2, will the match error out due to an unmatched subject, or will it pass 1 to F? function F(int $foo = 1) {} F(match(default) { default => default }); F(match($arg) { 'a' => 0, default => default }); Cheers Stephen
