with statement is a good feature. However, a lot of people including me believe that it lacks potential to be great.
It introduces scope and cannot be used in a declarative scope.
It’s shortcomings are surprisingly similar to C++’s
if constexpr that Andrei in Design by Introspection considered to be a “fatal mistake”.
Up for discussion, I’d even suggest a no-brace form for
with would be a great feature.
Contrary to others, I do not believe that
with expressions would be necessary. The main reason
with expressions are asked for is because
with introduces scope.
