Hm, no reason given, but one of the things I don't like about it is the
change in syntax it required.  With the advent of keyword parameters
(right?), and the ability to get the parameter names from within a
method, this should be trivial to implement on our own in 1.9 if Matz
doesn't want it as the default behavior.
