For that matter, too bad Grace Hopper didn't think of packages,
procedures with parameters, etc., in 1959!  :-)

Unfortunately, sometimes progress only comes by learning from our
screwups.  I think I can state with certainty that there is some
absolutely essential feature X such that a comp.lang.ada poster will
legitimately be able to say, at some point in the future, "too bad
Taft, Brukardt, Duff, et al. didn't think of X in 2005".

Oh, well...
