where the foo/bar/... bindings are not only useless but can prevent
the GC from collecting that memory (i.e. it's a representation that is

Compiled closures don't suffer from this problem because `cconv.el`
actually looks at the code and only stores in the compiled closure
those variables which are actually used.
So, we fix this discrepancy by letting the existing code in `cconv.el` tell
