If one edits a .c or .h file, one must rebuild to test. If one edits a
.py module, one does not, and it would be a major nuisance to have to.
My first suggested patches on the tracker (to .py files) were developed
in my installed version (after backing up a module). I have
occasionally told people on StackOverflow how to edit an idlelib file to
get a future change 'now'. Other people have occasional reported there
own custom modifications. If Python usually used derived stdlib code,
but could optionally use the original .py files via a command-line
switch, experimenting with changes to .py files would be easier.
