See, even Python supports this. :-)
And D supports the "with" statement in python, in the form of
"scope()" statements. The D way is slightly less misleading too,
as
with somethingThatFails() as e:
print(e)
doesn't make it obvious that neither __enter__ nor __exit__ will
be called if you raise an exception in the creation of the
object, or that if you raise an exception in __enter__, then
__exit__ won't be called.
auto e = somethingThatFails()
scope(failure) cleanup(e);
makes more sense to me, since it's blatantly obvious that the
construction (and entering) process isn't covered by the cleanup
routine.
