953	Numbers-egg version of signum should accept complex numbers	johnwcowan	sjamaan	"Common Lisp defines `signum` on a non-real number as returning a complex number whose angle is the same as the angle of the argument but whose magnitude is 1.  This degenerates to the standard definition for real numbers.

No change is needed to the standard version."	enhancement	closed	major	someday	extensions	4.8.x	fixed
