Not only they are not needed, it's also the wrong way of handling this as it is 
well known that factoring out module dependencies as functors doesn't scale in 
practice. The question to ask yourself for using a functor is: do I need 
multiple instances of the functor in *the same program* â good examples: 
{Map,Set}.Make.

See http://www.cis.upenn.edu/~bcpierce/papers/modules-icfp.ps for more on this. 
 

Best,
