It is a point here, that debugging is often a focused, time-intensive affair on a
non-production platform. Granted that there may be inherent challenges in the
code that I cannot predict, it seems to me that a knob in the Method object 
permitting you to turn on an 'auto-reload' that uses stat() EVERY time the 
Method is accessed would be an invaluable tool during the writing/debugging
phase. Obviously this would have to be disabled subsequently, before the
Method is used in a production environment, but for someone trying to debug their
code, a stat() is a hell of a lot less overhead than having to surf to the Method, reload
and surf back to the test spot!
