"Many projects used their own languages or special variations of
existing languages. This virtually locked the (DOD) into contracting
the original developers of a system for all maintenance work arising
during the life of that system." Cohen, "Ada as a Second Language",
1986, p. 2 on the history of Ada.
As a person who spends a fair amount of time testing portability of
new code, and working around the bugs and limitations of 5 different
"Ada 95" compilers, I'd suggest that anyone thinking of locking
themselves into a vendor-specific "special variations of existing
languages" look very carefully before they leap.
