If people adhere to the package versioning policy, then there cannot be 
collisions. That is,

   import Data.Bits

requires strict version bounds (>=x.y.z.w && <x.y.z+1)

and both of

   import Data.Bits (zero)
   import qualified Data.Bits as Bits

allow lax version bounds (>=x.y.z && <x.y+1).

Btw. "rotate" may already cause collisions with geometry libraries.
