The shell is extremely useful for prototyping and developing server side
scripts including map/reduce or other long running data manipulations
without the need for a separate language or scripting environment.

However, there is currently no easy way (at least that I could find) to
easily pull in libraries of java script functions for repetitive tasks.

Adding the equivalent of #include to pull in function/structure or other
definitions from external files or a classpath type argument so that
such functions could be searched for and loaded at runtime would
round out the console shell into a robust testing and data manipulation
tool.
