Its mostly for CTFE, not stuff your general dev will touch even in D.
Like generating javascript from data models or routes [0].

Summary:
"Helper functions" where by they have one task that does not change, and 
can be gained purely from the parameters given (mostly template args).
"Generator functions" where by they do some task that requires "helper 
functions" but cannot be ran at CTFE or generate code to be ran at runtime.

I started writing a small booklet on this, if you got an email if you're 
interested or some way to send you. Please let me know.
