Dear Language authors, please stop using single-letter names or generic terms for programming languages. It messes with the Google.

Duckduckgo seems to offer reasonable results: http://duckduckgo.com/?q=L. While it doesn't solve this problem entirely, it's a good starting point.

This name collision is even worse than you suggest. Lindenmayer systems (L-systems) were invented back in the 60s and have been called L-systems for years.

Actually, I followed the link because I thought this was referring to a programming language derived from them.

Indeed, that's what I thought of. The problem for R is so bad, people have created special purpose search engines like www.rseek.org .

J has an excuse. They only use identifiers longer than 1 letter because ASCII lacks for APL symbols.

Looks a bit like my Fexl (http://fexl.com/code), though Fexl has a much smaller grammar and footprint. I'm not sure I have all the "capability" and "distributed" stuff though, and I definitely don't have threads, much preferring "fork" (i.e., O.S. level blocking system calls with timeouts are my friends).

(Incidentally, GA Tech is my alma mater.)

Some code, which I haven't tried yet, at http://home.cc.gatech.edu/tony/61
