My initial thought was that it seemed easy, but then my next thought was 
that a lot of M::B assumes certain semantics about the layout of a 
distribution (e.g. lib, t, META.yml, etc.)  that aren't so easy to 
generalize to a recursive case.

It would seem fairly trivial to add a "recurse_into" parameter with 
directories but then what?  Are each of the directories mirrors of a 
normal distribution with their own lib and t directories?  And how 
should building/testing/installing work?  Copy all relevant files from 
all recursive directories into a top level blib directory?  Or should 
there be blibs in each directory?  Should top level tests assume the 
existence of (and know how to find) files from lower down in the tree?

Maybe this is an in-joke or todo from years ago -- but has anyone 
actually drafted a spec for how this should work?
