"PL/I has had type definitions for a few years now. You no longer need
to kludge using LIKE. It also has had enumerations, etc., for a few years
too. These first appeared under OS/2, but the Windows NT compiler has
them too, as does the latest mainframe compiler."

I thought PL/I had just structural typing, and not named typing, but
if we are talking about what people implement today, as opposed to
the standard, I may well be out of date!
