Implementation thoughts

We should never turn a verb into a noun when the verb is grammatical. The particle to before the verb is probably quite reliable though there's a change there might be cases where it could look like a preposition before a noun.

We probably need a special linter or class of linters for deal with phrasal verb / compound noun pairs. They would mostly share the same logic and heuristics though a few could have special false-positive cases. In the end we might want a separate curated dictionary of these, but we may be able to manage without one.
