Get rid of try/catch keywords while you're there?
While I'm meant to be doing other things, I just took five minutes to propose a random idea I had to remove `while` as a keyword from Scala. https://github.com/lampepfl/dotty/issues/5440 … Someone tell me if I'm barking up the wrong control structure...

I don't think we have an alternative way of implementing their magic in library code, though... even if we did start using monads for error handling everywhere.

I'm not proposing to remove its functionality... just to implement it in a standard-library method.

My main use case for while in scala is to save on object allocation. Will this be less of a problem in dotty?
-
Yes, though note that I'm not proposing anything which would require changes to anyone's existing code.

Interestingly, the dotty docs illustrate the use of the inline keyword with an inline def foreach that uses a while loop internally: http://dotty.epfl.ch/docs/reference/inline.html …

And dotty inline recursive methods require that the recursion level is compile-time constant. So replacing while with a tailrec combinator would still rely on JIT inlining, which even with graal is problematic for short loops.
