Hi,
I noticed someone talking about the various ways the `default` keyword could be
used in an expression including in match() and looking in the RFC examples I
see it is listed, so I think it's useful to clarify here. 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
