A newbie question about idiomatic Racket code: 

Suppose I wanted to create several numeric modules that all had their own 
interpretation of what addition means.  If each of them uses a (provide ... 
+ ...) form, the various "+" exports are going to collide in client modules 
that (require ...) more than one of them.

Is it idiomatic Racket usage to prefix the individual "+" functions inside 
each module like the built-in floating point  modules do (e.g. "fl+") or to 
assume client modules will use something like (require (rename-in ...)...) 
or (require (prefix-in ...) ...) to handle any collisions themselves?

If anyone can point me to example Racket code where this issue has been 
idiomatically handled that would be very useful.

This is also a good opportunity to say how impressive the level of 
documentation and support is in the Racket community. Thanks!
