x = z.real_part()
y = z.imag_part()
test = vector((x,1,1))
test = vector((x,y,1))
test = vector((z.real_part,1,1))
Last line causes an error, can't find common ring for all elements.
These variables all have type "Expression"; but some expressions denote
complex numbers and some denote real numbers. How do I tell sage about that?
