EXPERIMENT: Make async fn, .await, async move? { legal on 2015 #64286
Description
The parser currently will not parse async fn, async move? $block, and <expr>.await on Rust 2015.
Check whether:
- doing so would simplify the parser & the grammar.
- it is feasible with a crater run for
<expr>.awaitandasync move? $block
Drawbacks include:
- folks having fewer incentives to use Rust 2018.
