<masak> rakudo: class A { method foo { 'abc' }; A.^add_method('bar',
A.^can('foo')); }; my $x= A.new(); say $x.bar(); say $x.bar()
<p6eval> rakudo : OUTPUT«abc␤No candidates found to invoke for method
'foo' on object of type 'A'␤[...]
<masak> <takadonet> only works once :(
* masak submits rakudobug
<masak> if jnthn were here, he'd say that this result isn't so
strange; becuase .^can gives the dispatcher to the 'foo' method(s).
<masak> call it once, shame on... shame on you. call me tw... can't
get called again
<takadonet> it's strange
<masak> as with string encodings, dispatchers are there whether you're
aware of them or not, and whether you want/like them or not.
