Hi All,
Why does this work
$ p6 'sub RtnOrd( Str $Char --> Int ){return ord($Char)}; say
RtnOrd "A";'

But this does not?
$ p6 'sub RtnOrd( Str $Char --> Str, Int ){return $Char,
ord($Char)}; say RtnOrd "A";'
===SORRY!=== Error while compiling -e
Malformed return value (return constraints only allowed at the

------> sub RtnOrd( Str $Char --> Str⏏, Int ){return $Char,

Many thanks,

No pointy:
$ p6 'sub RtnOrd( Str $Char ){return $Char, ord($Char)}; say RtnOrd
"A";'
(A 65)

Precedence. `--> (Str, Int)` might work better; right now it can't tell
if you meant that, or intended the usual meaning for a comma which would
separate parameters.
