Interesting point, but an issue we seem to already have with SIZE( ).  We allow SIZE(ARRAY) where ARRAY is assumed-rank, yet the description of SIZE prohibits an assumed-size ARRAY in SIZE(ARRAY).

This would be change from the existing standard for C_SIZEOF( ) where the argument is assumed-size.  I think a better approach would be to restrict assumed-rank dummy arguments to not be associated with an assumed-size object in the ARRAY argument descriptions for both SIZE and C_SIZEOF. 

Cheers,
