In a way, yes, but not quite the same, since multiple calls to the
nested function would still redirect to the same block of code rather
than being inlined at each call. I suppose more similar to the old
GOSUB; RETURN combination in old versions of Basic, and the nested
routine slotted either at the end of the parent function or, if the
compiler is intelligent enough, right after one of the function calls
(in effect, inlining it at this point) so the peephole optimizer can
then remove a zero-distance jump.
