Can someone verify that this is a bug? Any hope a fix? (This is with
sage-4.0.2 on sage.math.)
{{{
sage: complex_plot((x^2 + I).sqrt().real_part(), (-2, 2), (-2, 2))
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call
last)

expression.so in sage.symbolic.expression.Expression.operator (sage/
symbolic/expression.cpp:15127)()

PS. The following quits with a less than clear error message; it
would be nice if there was some input checking.
{{{
sage: complex_plot((x^2 + I).sqrt(), (-2, 2), (-2, 2)) # I forgot the
real_part
}}}
