These are implemented now. (Mostly untested so far.) They should work 
the same as in Q, except that realvalp considers any complex value with 
zero imaginary part a real value. (In Q realvalp requires that the 
imaginary part is an exact zero, which would be rather inconvenient in 
Pure because that rules out most complex values in polar representation.)
