Java with this proposal will prove to be more expensive in the long
run. It's
like erased generics all over again.
The expensive version of pass-by-reference is already supported
using java.lang.reflect.Field.
And per the statistics posted in
<http://mail.openjdk.java.net/pipermail/core-libs-dev/2014-March/025531.html>,
the slightly faster pointer-to-field-member support is one of the prevalent use
cases for sun.misc.Unsafe. That's why I share Jeroen's puzzlement.
Sorry, I'm not sure what usages you have in mind, or
what constructions and implementable JVM mechanics
could be used to deal with them?
