Looks to me like the eval(repr(obj)) loop spanks XMLRPC. It likely also
spanks Gherkin, but I'm not one to run untrusted code. Give it a shot
on your own machine. As for parsing, repr() of standard Python objects
is pretty easy to parse, and if you want something a bit easier to read,
there's always pprint (though it may not be quite as fast).
