Comment (by simonpj):

 > This is all so brittle...

 I agree that brittle-ness is bad.  Can you stand back and give a
 description of the brittle-ness?

  * Of course, if a function is inlined, it can be specialised for the call
 site, and without pragmas that decision is indeed dependent on how big the
 function is. I see no way to avoid that.

  * But pragmas should not be brittle.  Can you show an example in which
 they seem to be.
