P.S. Or, it would be quite sufficient to be able to get the list of the
closeables inside of the try-with-resource. I mean something like
===
static List somethingSmart() { ... }
...
def a=new Foo(),b=new Foo(),c=new Foo()
try (a) {
assert somethingSmart()==[a]
}
try (b,c) {
assert somethingSmart()==[b,c]
}
===
Does Java or Groovy allow to write such kind of “somethingSmart”? How?
Thanks,
