Sorry if the question has been answered previously, but where is this
"InputModule" defined?

I'm worrying about possible namespacing issues with future cocoon
blocks.

between these I prefer #1. #2 seems to imply that the trailing path has
an effect on the use.

what is a 'module' in this sense?

between #3 and #4, the same consideration above apply. #5 is even worse:
it seems to imply an entirely new protocol and might conflict with
cocoon blocks in the future.

Much easier: force variable names *not* to contain a colon. It works for
XML elements and people using XML stuff are used to the notion of colon
as a namespaced prefixed declaration.
