Re: Ref to Method?

can returns a code ref - but you have to emulate the class/object invocation ... does this help ?

Running this:

package foo;

sub bar { warn "$self(@_)" }
sub tell { $ref = \&bar; warn "$ref" }

package main;

$ref = foo->can('bar');
warn "$ref";
&$ref('foo');
foo->tell();

results in...

CODE(0x914dfb8) at tst.pl line 9.
(foo) at tst.pl line 3.
CODE(0x914dfb8) at tst.pl line 4.

A user level that continues to overstate my experience :-))

That may be more obviously a method call as: `my $ref = foo->can('bar'); warn "$ref"; foo->$ref(); foo->tell();` [download]	[reply] [d/l]
