I think the feature you are proposing will likely be necessary either way.
It can also make the output of debug_zval_dump() reliable as
implicit separation of zval instances results with bogus reference
counts.
There were some good reasons not to implement this change and it definitely just complicated things without giving a real gain.
Making debug_zval_dump() reliable is not a good reason.
Well, then we'd better off getting rid of extract(EXTR_REFS), which would
(and will) never work as advertised.
Yet I'm still wondering how complicate it will be if we introduce a new argument modifier with which non-variable scalars are just passed to the function as usual, and variables are passed the way as if it was forcefully referenced.
