I have a bunch of methods in a base class, and cycle through some of them in a sub-class using can(), and I wanted to see if this would work to skip some of them:
package Foo;
use strict;
use warnings;
sub foo { print "foo\n" }
sub bar {
my $class = shift;
if ( my $f = $class->can("foo") ) {
print "yes, I can foo\n";
$f->();
}
}
package Bar;
use strict; use warnings;
our @ISA = "Foo";
sub foo;
package main;
use strict; use warnings;
Bar->bar();
# OUTPUT:
yes, I can foo
Undefined subroutine &Bar::foo called at ./test_foo line 17.
I know there are other ways to accomplish what I want, but what do you think would be the best way, and would you condsider the above behaviour to be a bug? For now, I'm just declaring an empty foo() function in Bar:
sub foo {}
Update: moved bar() to better simulate actual code.
Maybe "disinherit" would be a better word :-)
