I can now find the C+@ programming language. So it's not heavily special cased for common programming languages.

Google Code Search (2006-2013) [1] was more useful. I miss that. Its search allowed regular expressions.

It doesn't seem to work perfectly. Doing a verbatim search for "C+@" programming language produces a lot of results without the "C+@" on the page.
