The root issue is extensibility. The same sort of arguments come up with the simplest extensible language: Forth. There are whole categories of embedded applications where Forth can cut the development time down to a fraction of what it would take to do it in C. Once that programmer leaves it takes a long time for someone else to come up to speed to do the sort of simple modifications that such applications tend to require. ... and where do you get a programmer that can do anything effective with an extensible language anyway? Such people tend to be very good programmers in general and are rare and expensive.
