this weekend i experimented with google's go a bit. i kind of like it and i am looking forward to version 1.0 at the beginning of next year. i also checked out scala a bit recently. it looks like a nice alternative to java.

i thought a thread about non-mainstream (or even esoteric) programming languages would be interesting. laugh

what languages that aren't in the top ten here do you like (delphi, lua and actionscript don't count either)? did you use one for a real project?
