C does now have `_Defer` though for running cleanups at the appropriate time,
we have lifetime analysis in C, and we have `__attribute__((cleanup))` (though
that's on a declaration of a variable and shouldn't matter here). Given that a
common idiom in C is to take the address of the compound literal (because it's
an lvalue, unlike in C++), I think we have to be careful about getting cleanups
correct.
