Hi there,

sub foo { return ([1,2],3) }; my ($a, $b) = foo(); say $a; say $b;
1 2
3

sub foo { return ([1,2],3) }; my (@​a, $b) = foo(); say @​a; say $b;
1 23
Use of uninitialized value

part of discussion​:
Jonathan Worthington​: I guess if it's a signature binding, then the $b
would get the 3...
Jonathan Worthington​: So I think Rakudo may well be wrong here.
<...>
ihrd​: > sub foo { return 1,2 }; foo();
too many arguments passed (2) - at most 1 params expected
Jonathan Worthington​: hmm
ihrd​: I think this is error message not so informative
Jonathan Worthington​: Well, I think we just don't properly support
multiple return values.
Jonathan Worthington​: As in, unimplemented. That should eventually
work, not give any error.

The RT System itself - Status changed from 'new' to 'open'

From @moritz

multiple returns now work properly, and plenty of tests for them pass.
