Anyway, the larger point is that a re-entrant general solution is desirable. The sort example might be a bit misguided, because who calls sort-inside-sort[0]? Nobody, realistically, but these types of issues are prevalent in the "how to do closures" area... and In C every API does it slightly differently, even if they're even aware of the issues.
[0] Because there's no community that likes nitpicking like the C (or C++) community. I considered preempting that objection :). C++ has solved this, so there's that.
