Comment #17 on issue 1291 by Vinzent.Steinberg: reduce the import sympy time
http://code.google.com/p/sympy/issues/detail?id=1291
I agree. We should definitively not spend time on optimizing the import

i too find expected_fail a better name than xfail.
Also note that xfail does not seem to work with option --boxed

then if all is ok, make the final release.

Maybe let's get rid of those xfails altogether? It'd kind of difficult to

Hi,

removing hacks is always good news, but I do not agree that
