So I'm finally starting to implement multi-level invocants in MMDs.
I'd like to sanity check some cases first, though.
Are these two assumed to be identical?
multi sub foo ($x, $y)
multi sub foo ($x, $y : )
But these two are _not_ identical?
multi sub foo ($x : $y : $z)
multi sub foo ($x : $y : $z : )
Is multiple colons usable in invocation? If yes, is these two
assumed to be identical?
$a.foo($b : $c);
foo($a : $b : $c);
S12 says all the following cases "come out to the same thing":
$handle.close # 1
close($handle) # 2
close $handle: # 3
close $handle # 4
Does it mean that during invocation, when there is no colons and
no dots, an implicit colon is added at the end, making all arguments
same-level invocants and subject to MMD? That is, these are identical:
foo($a, $b)
foo($a, $b : )
But these two are _not_:
foo($a : $b : $c)
foo($a : $b : $c : )
Thanks,
