 Current solution: only do the "method sharing" thing for the first type/dict
 application, not for the iterated ones.  A horribly subtle point.
 
-Note [No method sharing]
-~~~~~~~~~~~~~~~~~~~~~~~~
-The -fno-method-sharing flag controls what happens so far as the LIE
-is concerned.  The default case is that for an overloaded function we 
-generate a "method" Id, and add the Method Inst to the LIE.  So you get
-something like
-	f :: Num a => a -> a
-	f = /\a (d:Num a) -> let m = (+) a d in \ (x:a) -> m x x
-If you specify -fno-method-sharing, the dictionary application 
-isn't shared, so we get
-	f :: Num a => a -> a
-	f = /\a (d:Num a) (x:a) -> (+) a d x x
-This gets a bit less sharing, but
-	a) it's better for RULEs involving overloaded functions
-	b) perhaps fewer separated lambdas
