Everyone I talk to seems to love clojure, I need to find an excuse to
use it myself.

This should be easily implemented using a new header argument (languages
are free to define new header arguments as they see fit).  For an
example of a language passing command line options through header
arguments, see the org-babel-ditaa.el file which defines a :cmdline
header argument allowing arguments to be passed to the ditaa command as
in the example below where the -r and -S options are passed to the ditaa
command.
