I am looking for an LTO tape library. Do you have one to spare?

p5-Safe-Isa 1.000005 devel on this many watch lists=0 search for ports that depend on this port
Call isa, can, does and DOES safely on things that may not be objects

Also Listed In: perl5

Since Perl allows us to provide a subroutine reference or a method name to the
-> operator when used as a method call, and a subroutine doesn't require the
invocant to actually be an object, we can create safe versions of isa, can and
friends by using a subroutine reference that only tries to call the method if
it's used on an object.

e.g. my $isa_Foo = $maybe_an_object->$_call_if_object(isa => 'Foo');

Note that we don't handle trying class names, because many things are valid
class names that you might not want to treat as one (like say "Matt") - the
is_module_name function from Module::Runtime is a good way to check for
something you might be able to call methods on if you want to do that.
