Let's review. Three reasons for function* syntax:
1. Opt-in required for backward-incompatible definition of 'yield' as
low-precedence unary prefix operator.
2. Zero-yield (no yield in body) basis case, useful for delegation via
yield* from another generator.
3. Decorator to alert the reader that the body contains yield (ignoring
2 for a moment) reason.
You are "bikesheddingly" supporting 3, I take it. Can you say more about
why you want a decorator for human readers? Again ignoring 2, which
makes the case based on what the JS engine must see, a more "objective"
criterion in this case (and, in a different light, in case 1).
