Sorry, I'm afraid I'm still not getting it. I can see how it would be possible to pass the request object to each function within my custom module, and then decide if it's appropriate to import the GAE-specific routines. This conditional import would need to happen in every function within my custom module, correct?
But it would be nicer to avoid duplicating that import -- if it's possible to do the conditional import at the top of a module. It seems to me that a conditional import statement at the top of a custom module cannot successfully reference the request object -- because it is not contained in a function, so I don't know how to pass the request object to the module - is that possible? Or is there another way to determine if it's running on GAE?
