Hey, I made a similar suggestion (minus the ThreadLocal) a few weeks ago, although for slightly different reasons. [1]
It should be noted that your async macro does in fact use the dispatcher just like a normal go would, the only difference is that it will start executing immediately in the current thread until the first "pause" instead of dispatching. After the "pause" the dispatcher will run it though which is not guaranteed to be the same thread. Therefore I'm not actually sure a ThreadLocal will work. Did you test that you get the actual correct result? Your benchmark is also not very useful, you are basically just measuring the frameworks overhead which is tiny to what it provides. In actual programs most of the time will not be spent in core.async internals, at least not from what I have observed so far. go blocks are actually pretty cheap.
