Comment (by ppurka):
What are the possible inputs of the `parent` keyword? For example, it will
still crash if `parent=int` or `parent=Integer`. I think it should be
modified to return `complex(y)` only after either doing something like
this
{{{
try:
return parent(y)
except TypeError:
if hasattr(parent, 'complex_field'):
return parent.complex_field()(y)
else:
return complex(y)
}}}
or, by doing something like this:
{{{
try:
return parent(y)
except TypeError:
try:
return parent.complex_field()(y)
except TypeError:
return complex(y)
}}}
