Prismatic Schema - Why is "both" deprecated?

[JvJ]

I've noticed that there is the function "both" in Schema.

Both says that it can be replaced by conditional, but I'm not sure exactly how to go about doing this.

Can someone provide an example?

Thanks

In place of (s/both long (s/pred odd?)) you can do (s/conditional odd? long), but (s/constrained long odd?) probably provides better error messages (since it validates long before odd?). I think there are some examples in the readme. 

If this isn't what you're looking for, can you please provide some more details of your use case? 

Thanks,

Jason

In this example, one of the schemas is a predicate schema.  What if neither of them are?

[Jason Wolfe]

Yes, that use case (two different non-predicate schemas) is no longer
supported. While superficially simple, it added a fair bit of
complexity and had corner cases that are not present with
`conditional` or `constrained`. Moreover, in our experience the
primary use case for `both` by far was with a predicate, and in the
other cases there is typically a reasonable alternative. Can you
elaborate on what your use case looks like?

Thanks, Jason
