Since I won't be at meeting 184, I thought I'd mention this. I submitted 
a paper about guarantees against copy in/out for simply-contiguous 
actuals. I just remembered we also have sequence association. I believe 
copyless argument passing should apply to sequence-associated arguments 
as well. I think this follows from the words (pasted below), but someone 
please check this and bring it up during the meeting.

Copyless argument passing is guaranteed if...
the dummy argument has the TARGET attribute and does not have the
VALUE attribute, and it is an explicit-shape array, an assumed-shape
array with the CONTIGUOUS attribute, or an assumed-size array, and the
effective argument is simply contiguous and has the TARGET attribute
but is not a coindexed object.
