Comment (by sgraf):

 That's what I was referring to by 'at the expense of even worse code
 bloat'. The difference is that you might have a better time being less
 precise for loopified bindings (have more bloat there) than to have
 potentially little more bloat for //every// non-recursive binding.

 Also depending on how far you are with your changes to !SpecConstr, this
 could be simpler.
