Is there ever an instance where we'll need to prettyprint an interface?

[jmcardon]

Probably yes for debugging. Thanks for the note, I'll remember to add pretty instances.

For transparency: These pretty instances are being used during integration work to debug the pact-5 representation of the modules read in from legacy. They're incredibly useful to see how we are deserializing things, but only modules presented a challenge, since interfaces are relatively simple.
