Multiple validators for an attribute

[cbornet]

It would be very handy to be able to validate an attribute against a list of validators.
This way they can be composed easily
Eg :validator: [instanceof(float), max(2), min(0)]

I was surprised this didn't "just work" when I tried it, honestly.

this is a duplicate of #13. we’re still trying to come up with something really good and lasting. It seems like this road leads to re-implementing a validation framework which seems like a waste of time.

[cbornet]

Yes, #13 looks similar. But a accepting a simple list of validators looks cleaner to me

[hynek]

You’re right, I’ve added it. A bigger solution is coming but this can be achieved w/o external dependencies.

For those that get this via Googling: https://www.attrs.org/en/stable/api.html#attr.ib

tl;dr: passing a list of validators now works (since 17.1.0)
