	Besides the fact that the "constructor" is __new__(), and __init__()
is an initializer of the constructed object (rarely does one really need
to supply __new__() )... there is a difference from __init__() and
_init_()... The latter is just a "use at your own risk, none public
convention" name.

	Double underscore at beginning and end are Python special names.
Double underscore at beginning is a Python mangled name. Single
underscore at beginning is a programmer convention for "internal use
only".
