Is there an altcoin with extended script operations?

[halftimepad]

Bitcoin programming capabilities with script are interesting, but a bit limited. You can play with most on the testnet, but there are still disabled opcodes (usually for good reason):

Is there any altcoin out there that has an extended set of opcodes in script to do different things that Bitcoin?

It could be anything from accepting some of the disabled opcodes to using new primitives.
