Hi All,
What is the syntax for returning two variable from a sub?
> sub x(--> Int, UInt) { return(-2,4) };
===SORRY!=== Error while compiling:
Malformed return value (return constraints only allowed at the end of
the signature)
------> sub x(--> Int⏏, UInt) { return(-2,4) };
Many thanks,

The guys on the chat line gave me a work around:
subset Tuple where * ~~ (Int, UInt, Str);
sub f($a,$b,$c --> Tuple) { ($a,$b,$c) };
say f(-1, 'x', 5)
# out of order, fails.
And I just added:
RFE: returns for multiple variables #152

And thanks to the guys on the chat line, I hvae a pretty
workaround.
