That is not a benefit. What does it buy you? Absolutely nothing. What
does it cost you? A lot of clarity. It invites memory leaks, refcount
bugs, accidental sharing of things you meant to have your own copy of,
sometimes accidental copying of things you meant to share, and worse,
all because you're wilfully and gratuitously blurring the distinction
between a value and a pointer to a value.

If you want to think in Java it's your lookout but please don't force
it down everyone else's throat.
