spews warnings with recent Object::Pad: Object::Pad::MOP is experimental ...

[jonassmedegaard]

Calls to Object::Pad::MOP spews errors since recently, as documented here.

Here's a fix:

Hi Jonas! Thanks for the head's up and the patch! Unfortunately I cannot accept it as is because "no if" only made it to core in perl 5.22.0 and Object::Pad's minimal version is 5.18.0 - and I don't want to add an extra dependency just to cover Object::Pad.

Could you update the patch so it works with older perls without adding an extra dependency? I know it's a bit of a pain but a lot of developers need to work on pretty wild codebases and I want DDP to be a tool for everyone. If you can't, just let me know and I'll try and come up with something when I have enough time.

Thanks!

Ohh, thanks for clueing me in on why App::Licensecheck 3.3.2 really fails, and why my fix for 3.3.3 won't do any good. I will try look for a better fix. - Jonas

I think you are mistaken: perl 5.18 documents the syntax proposed here, and tests for App::Licensecheck v3.3.4 using that syntax seems to succeed for perl 5.18.

@garu Can you elaborate on why you believe this won't work for older perls?
