Hello,

the change proper looks good, and is an improvement.  But I'm a little 
concerned by the production of references like in the test x1%vv%z which 
could be confusing and is strictly speaking invalid fortran (multiple 
non-scalar components).  Did you consider generating x1%vv(?,?)%zz or 
x1%vv(...)%z or similar?

There is another nit about the test, which has dg-output and 
dg-shouldfail despite being only a compile-time test.

Otherwise looks good.
