I'm still fairly shaky on Perl6 syntax, but in Perl5
>perldoc UNIVERSAL
gives:
can ( METHOD )
`can' checks if the object has a method called `METHOD'. If it does
then a reference to the sub is returned. If it does not then *undef*
is returned.
`can' can be called as either a static or object method call.
The fact that the above isn't exactly true (subroutines are not checked for
verify that the :method attribute is set) is beside the point.
I'd hope that $ref.method would return a true value. And that $ref would be
executed as a method.
