I reading more about this, and found this by Stef
http://www.iam.unibe.ch/~ducasse/Web/OldSmalltalkFiles/Singleton.pdf.
But something still seem unsolved if for having a needed behavior (what only
exist one instance of MyClassFoo) we have type (or copy) a piece os same
code several times.
Anyway, I follow you advice and thanks you.
