In a much earlier Lacinia, there was the idea of a resolver-transformer, but that ended up being silly, as you can just wrap your existing functions however you like before passing them into Lacinia with the schema.

One thing you can look into are scalars, since you would have the ability in the scalar's serialize function to do all kinds of interesting things.

I've been pushing, on our team, to have additional scalars for things like Currency (an Int, as number of pennies), a CustomerId (a String, with a particular regexp pattern) etc. The parse/serialize would often be trivial, but it's another place to push some global input validations, and (importantly to me) a good place to put some documentation.
