Well, yes, for Perl, but no for Python. Python Johnny said "sort[ing] by its builtin sort method without arguments", which makes us think GRT, but he also said "an auxiliary list is first built", which implies the general ST. As we know, arrays don't sort meaningfully with Perl's default sort. However, the Python default sort knows how to compare arrays. So to a Python programmer, the ST can be achieved using the default sort. But that still doesn't make it a GRT. -- John Douglas Porter __________________________________ Do you Yahoo!? SBC Yahoo!
