I know that until, say, 3 years ago, I wouldn't know a thing about parsers, and if they boss wanted a scripting language, I would have parsed the whole thing by hand in C. It would have been a total nightmare to maintain (and develop) and would have been awful.

Now I know about lex and yacc and I know what a parser really is. If everybody at the company was a bunch of random engineers or something with no experience with language design or parsers, its totally understandable that something like that could happen.
