1. Could I set multi-return type?like
sub test as (Int, Str) {...}
my (Int, Str) sub test {...}
or my (Int|Num, Str) sub test{...}
2. set is unordered collection of values， subset is new type. People are
apt to confuse

I'm thinking that the solution to this issue may be a little more
radical than to-date: don't permit junctions to be stored in $
variables! Instead, require junctions to use a twiggle, to alert the
reader that the surprises may be lurking.
my $x = 1|2; #error
my $|x = 1|2;

as is coercion - so to what would it coerce? Int or Str? How could the
compiler know? Or do you mean something like a tuple?

Note that people never write subset in their code, the write things like
sub f($x where { ... } ) and the where constructs the subset type. I
don' think that's
