Yep, I can imagine it would work really well, if the front-end implemented
the logic to factor out redundant inc/dec ref's.

It isn't the best idea to do this sort of optimizations (entirely) in the front-end, because you really want to be able to aggressively optimize away such redundant operations after inlining at what previously were function boundaries.

But then again, if you use AST-based inlining like DMD does, it might just work… ;)
