This is a good example of why you shouldn't program language X in language Y.

For starters, `intX.__str__` should be written as `str(intX)`;

For middlers, intX_asString is probably not necessary (is it being printed? then
do a `print intX`, or a `print "size left on disk: %d" % intX`, etc.

For finishers, why the System Hungarian Notation?

     intLength1 = 5   # feet
     intLength2 = 13  # centimeters
     .
     .
     .
     intLength1  + intLength2   # oops!

vs

     ftLength1 = 5
     cmLength2 = 13
     .
     .
     .
     ftLength1 + cmLength2  # hey, that's wrong! better throw in a conversion
