AFAICT this is already handled fine:
write(6,*) foo(1)%bar(1:1)%variable(:)(2:4)
         1
Error: Two or more part references with nonzero rank must not be specified at

I believe that some function which can find if an expression is really  a
contiguous array in memory is pretty useful. In the end, many optimization
