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
