Sadly it is true also, I read somewhere this silly point was used also to 
make distinction between java and python, then claiming python is just like 
another interpreter, while java has it's own (what they call as) 'compiler'. 
:)

perhaps in the future another sillly point could be added also, Java has 
Jython, while Python doesn't have some thing like PyJava or... perhaps Py-va 
(Python based Java Language).
