As far as I can tell IronPython 2 does not improve this case.

However, IronPython 2 does improve *seq case, more than a factor of
two, compared to IronPython 1. I have a plan to do a comprehensive
benchmark of call sequences for CPython, IronPython 1, and IronPython
2, based on callbench developed in PyPy. Ah, procrastination...
