display of lisp complex numbers in wxmaxima

  with set_display('none),
?complex(3,4)  displays as  #c(3 4)   which is, I suppose,  fine.
with set_display('xml),
?complex(3,4)  returns $C(3Space4) which is peculiar.

I suppose the rest of this note should be in a separate
message ....

There are subtle issues with representing 3+4*%i as a lisp
complex number.  For example,
  3.0b0+4.0b0*%i cannot be a lisp complex number.

But introducing lisp complex numbers into maxima sometimes
may be helpful. Extending bigfloats to complex bigfloats
may also be helpful.


  Does anyone actually need 1/(3+4*%i)  or can we always
clear the denominator ... 1/25*(3-4*%i) ?
