I said ��object oriented�� :p

Bah, let's got with lots of ifTrue:ifFalse: ...�� Hopefully, a kind soul will iterate on this and make it OO :-)

10 <=> 20.

Tag sort functions looks great to have around.

About the spaceship operator (<=>), is this something�� we'd like to have around? (I like it). http://en.wikipedia.org/wiki/Three-way_comparison

How would you make this ��object oriented��? Have three singleton objects ��Less��, ��Greater��, ��Equal�� (similar to ��True��, "False��), and on those object methods ��ifLess:��, ��ifEqual:��, ��ifGreater:��?
