Add a pretend.ANY

[dstufft]

So with the call recorder it's often a useful thing to be able to make a parameter that matches anything. Perhaps it's a current timestamp or a random value, whatever it is you don't know what it is.

Mock has mock.ANY and I'm finding myself installing mock just for mock.ANY.

I hate to do this, but I’d really love to see that too. 🐶

So the necessary code is:

class _Any(object):
    def __eq__(self, other):
        return True

    def __ne__(self, other):
        return False

ANY = _Any()

I still feel pretty weird about this, call_recorder may have been a mistake.

I'll +1 the request for pretend.ANY -- I'm happy to make the PR for this.

(I think my usecase is the exact same as @dstufft's, and this'll have the nice benefit of allowing us to remove mock as a test dependency in Warehouse's testsuite.)

Is there a reason writing the trivial block above doesn't work for you?

To expound: I really regret adding call_recorder, I don't think it matches the spirit of what I was going for with this library, and I fear that incorporating Any just compounds that mistake.

[woodruffw]

Nope, I can just reuse that. My only thought was to have it in pretend since it'll be used solely (in my case) with pretend's other APIs, but that's not a requirement.
