Hi !

If you want ABSOLUTELY a #power: or a #** method you should alias #raisedTo:

Number>>power: aNumber
   ^ (self raisedTo:aNumber)

The #raisedTo: method is more elaborated than a mere loop cause you
can reduce the complexity of a power calculus with logarithms. You
should really look at the #raisedTo: method...
