Summary : Call isa, can, does and DOES safely on things that may not be objects
Description :
How many times have you found yourself writing:

if ($obj->isa(\'Something\')) {

and then shortly afterwards cursing and changing it to:

if (Scalar::Util::blessed($obj) and $obj->isa(\'Something\')) {

Right. That\'s why this module exists.

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. So:

my $isa_Foo = $maybe_an_object->$_call_if_object(isa => \'Foo\');

is equivalent to

my $isa_Foo = do {
if (Scalar::Util::blessed($maybe_an_object)) {
$maybe_an_object->isa(\'Foo\');
} else {
undef;
}
};

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.

We are careful to make sure that scalar/list context is preserved for the
method that is eventually called.
