Extra notes from in-person discussion; 
We might want a both a Sync-REPL and Async-REPL `compile()` mode depending on wether the REPL support async. 

One of the other question was wether `exec` should look at wether an eventloop is running, or if it should just return a coroutine and it's the -programmer job to check wether there is an event loop or not and do the right thing. 

Also for info all the top level async-await PR and issues on IPython can be found here: https://github.com/ipython/ipython/issues?q=label%3Aasync%2Fawait+is%3Aclosed
