I agree it's a misuse, my point is simply why introduce the possibility?
Key question for me (for any feature): show how it can reduce the chances
Arrow functions succeed, for example: by removing nested "this" context,
thereby simplifying moving of code around etc.
Async await succeeds, for example: by linearizing and hence considerably
simplifying the building and reading of asynchronous data flows in code.
Classes succeed, for example: by removing the fiddly overhead in
establishing (especially multi-level) inheritance using prototypes.
The examples on the proposal page don't succeed, for me, in establishing
how (if at all) using a do-expression could (vs the most elegant
