Was having a similar idea, as I language I'd love to use with this is
my current fave clojure:

http://clojure.org/

It's a language based on the JVM and consequently being able to pass
in command line options to the interpreter is important...  I'd
imagine most of the time the source blocks within a single file would
share the vast majority of environment settings too (for example
setting the JVM's class path) so being able to specify these values to
pass to the interpreter, once at the top of the file would be really
nice.
