TR15581 - elemental assignment of structures with alloctable components

[Salvatore Filippone]

If I may add my .02 Eur, the shallow copy implementation of derived
types with ALLOCATABLE is so wrong (by default) that F2003 introduced
MOVE_ALLOC for those situations where the user explicitly wants
something (remotely) similar with an allocatable object.

Which brings me back to an important (to me) issue: please, please,
please implement MOVE_ALLOC alongside the rest of TR15581. 

Keep up the good work
