A given/when construct using a junction isn't quite doing what I'd expect.
I'd thought that that would confirm that both elements were Int:
say do given all(3,7) { when Int { "both are Int" }; default {"not
similar"} };
## not similar
But this does what I thought it would:
say so do all(3,7) ~~ Int;
# True
And the given seems to put the junction in $_ as expected:
given all(3,7) { say $_; say $_.WHAT; }
# all(3, 7)
# (Junction)
And you can use that junction in a smartmatch explicitly
given all(3,7) { say so $_ ~~ Numeric; }
# True
