with live programming in mind.  It supports interactive programming in a REPL
style, compiling and binding code just-in-time.  Although Extempore has its
roots in 'live coding' of audiovisual media art, it is suitable for any task
domain where dynamic run-time modifiability and good numerical performance are
required.  Extempore also has strong timing and concurrency semantics, which
are helpful when working in problem spaces where timing is important (such as
audio and video).")
