Advocates always say Type Checking, but so often it seems like Type 
Constriction. - To hell with it!
I don't believe I would be more productive by cluttering Python with the 
Type schemes and variable declarations found in languages like Pascal, 
C, Basic, C++ and Java.
People have said that there may be a more intelligent way, maybe type 
inferencing? But no, please, nothing like the above, it would just get 
in the way.
