Comment (by rkern):

 Hmm. You'll note, though, that the result is a matrix, not a single real
 or complex value. It is the result of finding the full covariance matrix
 of the 2-vector (real, imag). You really want to use {{{cov()}}}, not
 {{{var()}}}. Probably, we should just disallow complex values for
 {{{var()}}}.
