The purpose of isa_ok() is two fold:
Check that a scalar contains an object
Check that object is of the right class
and it only exists because it's a very common test and you have to do the
above in several steps to get good diagnostics:
ok( defined $obj, 'object is defined' );
ok( ref $obj, 'object is a reference' );
ok( $obj->isa('My::Thing'), 'object isa My::Thing' );
Whereas checking a class is much simpler
ok( $class->isa('Whatever'), "$class isa Whatever" );
Worse, it adds an ambiguity into isa_ok() with the small possiblity that
$obj might contain a class string and cause a false positive.
So I'm not convinced. Why did you find it useful?
