(j3.2006) deallocating pointer function results
Thu Nov 12 02:40:03 EST 2015
(IMNSHO) pointer assignment is to pointers as assignment is to nonpointers.
They are precisely analogous.

Basically, INTENT(IN) is designed to give you compile-time enforcement of
the restrictions that apply to expression actual arguments. These really
are supposed to be essentially the same.
>the standard is too restrictive
Sounds like you are suggesting a wart to me. DEALLOCATE doing a
pointer-assignment of NULL() to the pointer variable is an essential part of
memory management hygiene; in the uncommon case where one wants to invoke a
function and throw away the result (with deallocation), it is in my opinion
not too much to ask of the user that they capture the result in a pointer
variable and DEALLOCATE that pointer variable.
