@Seedfork, I definitely consider making leaf mold a variety of composting!
And I know what you mean about bagged, wet grass clippings in the hot sun, too. They do get stinky. But as I think you're also describing, I find the odor can be fairly quickly obliterated by balancing them in a pile with drier material.
Some of that smell, if not most of it, is ammonia which is the odor of nitrogen being released into the air. My mixture of alfalfa pellets and steer manure smells ammoniac at this point, quite intensely! But layered on the pile over fresh green stuff and topped with a covering layer of dry carbonaceous material, it doesn't present a problem at all.
