Mimics the behavior of Args#add_all's map_each callback and can be used to skip over values.

Also improves the error message when the callback returns an unexpected type by including the value.

@hvadehra Could you review? I found this small feature very useful while picking up computed substitutions.

Mimics the behavior of `Args#add_all`'s `map_each` callback and can be
used to skip over values.

Also improves the error message when the callback returns an unexpected
type by including the value.

We could probably get this into 6.1.0, right?
