URL: https://github.com/apache/groovy/pull/1994#issuecomment-1826386161
I am looking for better AST for pattern matching for both `instanceof` and
`switch`.
The PR is just for `instanceof`, but I try to make flexible to change easily
for other pattern matching and destructure.
The reason of adding pattern variable to `ClassExpression` is making the
change smoothly. As you known, all visitors process `ClassExpression` well, but
do not know new expressions, we could refactor later, let's make it work at the
beginning.
