A bit on the other side of the argument, I use grep plus find plus some shell work to do source code analysis for security reviews. grep doesn't really understand the syntax of languages, and that is mostly OK. I've used this technique on auditing many code bases including the C family, perl, Visual Basic, C# and SQL. With this sort of tool, I don't need to look for language-particular parsers--so long as the source is in a text file, this works well.
