I just tried a checkout of master, however I get the following:
ImportError: Python Version 2.6 or above is required for IPython.
Trying a little bit more by disabling that version check, I discovered that
at least 2.6's support of print as a function, instead of a statement, is
used. Now Jython 2.6 work kicked off just this week, so hopefully we don't
really need 2.6. Jython 2.5 does have two key 2.6 features that you might be
using: 1) full mutable ast support (through the ast module, used by sympy's
support); 2) class decorators. (We also have namedtuple.)
Maybe for Jython this is just a matter of isolating the print function? It
doesn't seem to be used in too many places.
