p5-isa

isa - is not the isa operator

The new isa operator in Perl 5.32 is pretty great, but if you need to support legacy versions of Perl, you can't use it yet. This module gives you isa-like functions you can use in Perl 5.6 and above. If you've got Type::Tiny::XS installed, you will probably find that this module is faster than the native isa operator! The functions exported respect inheritance and allow classes to override their isa method as you'd expect.
