Try a descendant in q/kdb+ at kx.com. No special symbol set required. For reference, "Q for Mortals" is a good read, and Joel at wagerlabs.com blogs about q/kdb+ occasionally.
q/kdb+ could turn into something really useful, and has some nice tricks, like very easy to use remoting capabilities, and a way to send lambdas to another machine anywhere and have that machine run the code. Unfortunately q/kdb+ are still a bit too domain specific to the finance world where the product apparently has a strong commercial following, so some of the stuff, like a robust, secure web server to compliment the powerful remoting capabilities is currently not available. Additionally, the language should have separate variable creation and setter operators, because it would be pretty easy to inadvertently start working with a new var after a mistype when an original var was intended.
If this stuff was cleaned up for consumption by a larger market, I think it would be pretty hot.
