Comment(by nbruin):
The following doctest from calculus.py now goes wrong:
{{{
limit(-e^(x^2)*erf(x) + e^(x^2), x=oo)
}}}
Which stumbles at calculus.calculus.limit at these lines:
{{{
1122 return l.sage()
1123 return ex.parent()(l)
}}}
Two return statements??? A little {{{hg -blame}}} points to #7661. Indeed,
commenting out line 1122 fixes a lot of the limit problems. However,
Burcin put in that line for a reason, I assume, so I'm hesitant to just
commit a reversal.
Note that the issue of #7661 is exactly due to a namespace collapse from
SR -> Maxima; something this interface could eventually solve much more
elegantly, by just mapping (at no cost) SR.var('x') to the maxima
identifier "sage_SR_var_x".
