This is just a quick attempt at getting something going for #550. Anyone (e.g. @HKalbasi) is free to pick up my branch and work on this further, I might not have time for more for a while.

[ ] Add tests, especially for the newtype interaction
[ ] Add custom error variants / messages
[ ] Update the extension docs and grammar
[ ] I've included my change in CHANGELOG.md

Thinking about this some more and the challenges of this implementation draft ... I think this should not be an extension but instead a pretty printing option

this would allow all parsers to parse both the parenthesised and the braced syntax
it would simplify the parser because it would not need to suddenly make previously allowed cases fail
it would not require changes to RawValue
as a downside, it would not be possible (immediately) to only parse code that follows the new syntax
