Hi Janne,

Wouldn't it be even better to pass scalar intent(in) variables by
value? The obvious objection of course is ABI, but for procedures with
an explicit interface we're not following any particular ABI anyways?


The problem with that is that we don't know when we compile a procedure
if it will be called with an explicit interface or not.

The user can always add an interface block for a stand-alone procedure.

Regards

	Thomas
