Dozy and syseng68k, I am not trying to be alarmist - but I do find it very telling of the entire world of developing software, that tools like APL, FORTH, and Smalltalk, which are purpose-built for solving specific problems, are universally scorned in favor of bloated "software development universes" that operate according to internal laws that make string theory look sane. The problems get lost in the process of development and the software becomes an end in itself. The effects are most obvious when things go south, and one is presented with blizzards of useless information. It may be OK to wade through such dross while sitting in the data center, but pilots with a troubled airplane don't have time to think about such things.
