Comment (by simonpj):

 > I would be thankful for any suggestion about which part of the linter to
 modify in order to produce errors when applications of the {{{StaticPtr}}}
 constructor appear nested within other expressions.

 It's a bit awkward with the current structure of `CoreLint`.  I best might
 be

 * Make `lintCoreExpr` complain if if it finds a `StaticPtr` constructor

 * Make the non-recursive case of `lint_bind` (in `lintCorBindings`) call a
 new function `lintTopNonRec` or something.

 * `lintTopNonRec` can have a case for `(StaticPtr e1 e2)` on its RHS, and
 allow it.
