how come a program that runs directly doesn't need to be optimized
into bytecode first?  Or... is it that the interpreter will just run
the program as it goes by, without ever generating a .pyc file?   So
what if you have a program that you only update every few weeks...
then you can ask a .pyc to be generated so that it runs faster every
time?
