What i was trying to say is that if every time you wite to the data
block and it has to be checked to make sure its of the right type then
that slows down the program. If at all times you only write the data in
the correct way and type you should be able to read it and skip the time
consuming type checking step...

Just cuz its more readable dont mean it will be faster(and vise versa)
