No exception

Yes, it's not available on the root, only on the types. I see you took it from the documentation, it's fixed.

[rjdp]

thought so, thanks for the quick update!

[rjdp]

@Marsup but isn't .valid an alias of .any and .valid is present on the root

[Marsup]

Actually that's a fair point, my bad.

[rjdp]

I think I will change my code to use .valid on types only and not on root, coz future fixes for this issue might break my code, that makes sense ?

[Marsup]

You can do that in the meantime. I'll let @hueniverse see if my patch makes sense with his vision but other methods are there so pretty sure this one should too. Anyway you won't see a release immediately so it's best you move on with the longer form.

[rjdp]

much appreciated, thanks.

[hueniverse]

only() is no longer used as an alias for valid(). This is a breaking change in v16.

[rjdp]

missed to notice that in latest docs, thanks for clarification .
