Title: Add an `after_validate` block option

I have an array parameter that I need to run operations on each element after splitting them. Since splitting is performed in the validation step, I needed a transform block that would run after validation.

This pull request adds an `after_validate` parameter that takes a block and runs just like `transform`, but after validation.
