There are a series of possible improvemnts to SpecConstr, described in
 the source code.  {{{compiler/specialise/SpecConstr}}}

  *  Specialising for constant parameters
  * Specialising for lambda parameters
  * Two ideas to do with strictness that look more tricky

 Some of them look quite straightforward.
