What becomes of |
New syntax
A extends B, C { ... }
instead of
A extends B with C { ... }
The old syntax is still allowed, but it's planned to phase it out together
with `with` as a type operator.
Also: disallow
A extends { ... }
(make it a migration warning under -language:Scala2)
While doing these changes, applied some refactorings to handle templates
in the parser which hopefully make the code clearer.
I'd have a tendency to phase that out (in 3.1+). Replace it with a named class. |
