/* These are wrappers around the following idiom:
* assert(SOME_PRED(obj));
* do_something_with(obj);
* This works around the fact obj may be an expression with side-effects.
*
* To make this work with nested expansions, we need semantics like
* (let ((x 1)) (let ((x x)) x)) => 1, but in C, int x = x; results in
* undefined behaviour because x refers to itself. As a workaround,
* we keep around a reference to the previous level (one scope up).
* After initialisation, "previous" is redefined to mean "current".
