24629	Allow Func Expressions to be used as Transforms	Josh Smeaton	Josh Smeaton	"I can't seem to find a ticket mentioning this, though we have discussed it before. Please close if you can find a related ticket.

Func Expressions and Transforms are extremely similar in API, but not enough to be interchangeable. Transforms are 1-arity (usually - postgres.array.IndexTransform is a notable exception) Functions with special behaviour.

Instead of implementing a Length Func and a Length Transform, we should be able to implement a Length Func and register that same class as a Transform. That's not currently possible because of the slight differences in API and behaviour. We should resolve this ASAP."
