Might it also make sense to allow anonymous variables in the
try-with-resource statement?
So that something like `try (() -> System.out.println("closed")) {}`
would work...
I don't think that is necessary. In JDK 7, we started out allowing a
general AutoCloseable expression in a try-with-resources statement and
that proved problematic. Supporting a final / effectively final
variable seems to be the right balance. The rationale is written up in
the JSR 334 materials.
Yes, I agree. And it can easily be moved to the finally block, of course.
However, this:
ExecutorService executor = ...;
try (executor::shutdown) {
}
still looks a bit more attractive to me, comparing to `try (Closeable c
= executor::shutdown) {`
Maybe one day ... :-)
Sincerely yours,
