> It seems we’re all in favor of break-with over unadorned “break”?  

Just for the record, there are possibly-complementary options in this direction.  This is not a proposal, as much as putting them on the record.

 - Allow `break-with` as a synonym for `return` in lambdas.  Using `return` was an uncomfortable choice (but this may well be locking the barn after the horse escapes.)
 - `break-to` as a synonym for labeled break.  
 - `break-from for | while | do` as a synonym for “break from the innermost control construct of this kind” (as an alternative to creating a label.)  

Overall I don’t find any of these terribly compelling, but perhaps this may jog some actually-good ideas.
