[Cuis-dev] >> notation

[Hernán Wilkinson]

well, the right way to write would be:

Number>>#squared
...

Because the receiver is Number, the #squeared is an instance method. If it
was a class method it should be written:
Number class>>#squared
....

Remember that it is not syntax, it is a message send.

Hernan.
