This has been debated to hell and back. To make a long story short, here 
are two common use cases:

x = MyClass()
y = x
del x

objects = [MyClass() for i in range(100)]

If you can come with a meaningfull answer to "what's *the* name of any 
of the MyClass instance(s)" in both cases, then please let us know...
