PS: the whole namespace thing is very frustrating I think: 1. one identifier for your namespace, 2. another identifier catches the function-constructor, 3. another identifier is used to represent the actual object... hmmmmm
My-class just bypass step 1 and uses everywhere, even inside the constructing object, the identifier from step 2.
