Hmm, couldn't you do the same by making the keys `Schema()` instances and validating them separately?

I think it's better if we merge your "composer" idea, @rmorshea, since it can be used for different use cases, and then have a section in the docs where we...

Can you not already do this with an `Or() `?

Ah, the way Schema works you can validate key names individually, not in conjunction to one another, so you can't perform an action (deny) if another key already exists...

Would a custom error message not suit the use case here?

Oh, I see. In that case that might valuable.

Hmm, I'm not sure what you mean. Doesn't iterable accept both lists and tuples? I'm confused as to the reasoning behind the removal.

Can you post the relevant part of your schema? It looks to me that you aren't converting them to decimals.
