According to S02:1363, a return value not matching a constraint should
internally call C<fail>, which means the above shouldn't die immediately.
jnthn++ notes that this may be a deviation from the way type constraints
are handled by other parts of the spec; thus the spec may want changing.
If so, we can file a spec issue for that; in the meantime I'm filing the
rakudobug so it doesn't get forgotten.

Still the same in current Rakudo:
This is Rakudo version 2017.08-104-g76f1d8970
built on MoarVM version 2017.08.1-148-g1059eed1
implementing Perl 6.c.
Better test-case:
➜ sub abc() returns Int { 3.5 }; say abc.defined;
Type check failed for return value; expected Int but got Rat (3.5)
Since there has been no update on this, and no-one's complaining about the current behavior, does this mean the ticket should be rejected?
