While writing on the perl external method product I back ported its "Try It!" support to also work for python external methods that take arguments. The change is fairly simple. Clicking the "Try it!" tab takes you to a screen where you get a chance to fill out the arguments for the method before you actually call it. If the function takes no arguments, then things work the same as they do today. I introduced a "call" alias for "__call__" in order to be able to actaully call the method object from the DTML method. Is there a better way?
