Description

It would be great if we could have a included function that would test for class inclussion.

My use case: I currently have some definitions that doesn't make sense unless a given node includes a class related to those definitions (for example, think of class postgres::server and definition postgres::database}. I would like the parser to fail and log some custom error (using fail) if someone uses the definition without including the class, and the only way I can think of doing it is testing for definition of some resource only managed by that class, but that seems to be a bit shabby. A included function would cleanly solve this problem.

Okay - I can see the requirement - not sure how it'd be achieved. Luke - over to you if you want to add it and have time/inclination.

Just use this: 

if defined(Class[my::class]) { ... }
