deferrable epp function simplifying deferred templates #1253
Conversation
This function will detect when it's passed a deferred function and will effectively defer itself rather than rendering a template directly.

Never mind. I figured out the return type and submitted an rspec-puppet PR to actually allow this matcher to work.
