Yeah I may be the only one, but I still think async/await was a huge missed opportunity to get rid of promises like I proposed here for javascript:

It seems quite inneficient to me to wrap every function call in a caching layer and state machine that pretty much goes unused in the context of async/await and makes things unecessarily hard to undertand for new programmers.
