It has always seemed to me that PL/I would have been more successful
if the early compilers generated faster code (and ran faster, too).
It might have been that too much of the above was adopted, along with
other COBOL features, by PL/I. There are many things that other
languages, such as Fortran, traditionally didn't let you do, because
they might run too slow, but that PL/I allowed.
(Many of those have now been added to Fortran.)
Of all languages, I think I still find PL/I the most fun to write in,
though not necessarily best for the problems I actually need done.
