Using 4.6.2 in the notebook:
mod(2,990)^-1
Traceback (most recent call last):

exec compile(u'open("___code___.py","w").write("# -*- coding:

exec compile(u'mod(_sage_const_2 ,_sage_const_990 )**-
_sage_const_1
File "", line 1, in <module>
RuntimeError
Shouldn't there be something here about trying to invert something not
in a group of units, like a ZeroDivisionError type of thing? If this
happened in the middle of some huge computation, I'd be up a river
without a paddle.
Thanks for any insight,
