Yes, but pitfalls were added to the feature in Fortran '90 and it should now be generally avoided.

I strongly disagree. Arbitrary bounds are tremendously helpful in dealing with arrays whose starting point must be offset.

I didn't say that they were not helpful; I said they have dangerous pitfalls. Also, they're not perfectly portable. My testing shows that only two compilers get lower bounds right in all the tricky cases that I know of.
