By reading a comment: "Not defined on Complex numbers"
i wonder why implementation is different than following:
Complex>>
< aNumber
"Not defined on Complex numbers"
self shouldNotImplement
;)
But yes, given the fact that Complex numbers could be used by someone
in code as real numbers, and therefore expecting #< to work, an
implementation proposed by you is plausible.
