rakudo​: multi s (Int $x) { ~$x }; multi s (Str $x) { $x }; say &s.arity
rakudo 31d41e​: OUTPUT«Method 'arity' not found for invocant of class
'Perl6MultiSub'␤ in main program body at line 22​:/tmp/iCLjYkQl5A␤»

.count and .arity are not implemented on multisubs. Their meaning on
multisubs should be unambiguous--.arity returning the minimum arity of all
the candidates and .count returning the maximum count of all the candidates.

@coke - Status changed from 'new' to 'open'

From @pmichaud

Now implemented in nom, need a spectest.

Note that the spec has changed somewhat since the ticket was originally
entered -- .count/.arity on a multisub proto returns the count/arity of
the proto itself rather than looking at the multicandidates.

From @moritz

Now tested in S06-signature/arity.t

@moritz - Status changed from 'open' to 'resolved'
