Where to look for the Next cool language

Ever heard of a finance company that had its own programming language.

Morgan Stanley seems to have had its own language A+ developed inhouse for high performance analytics work. Originally developed as an replacement for the Array Processing Language (APL) on Unix platforms, A+ seems to have had become the central language for building Morgan Stanley's analytics applications and real-time trading systems in the early '90s.
