does "become" only exchange references ? Or is it more to it than that ?
where I can find information about what insance enumeration and reified
stack frames are ?
Python has methods in gc module (module for its garbage collector) to find
objects that point to an object or objects that an object point to . But it
has no convenient method to exchange those references . I assume you could
do it via an iteration but I never tried it in practice.
Indeed such feature is essential for live coding. I will have to add it to
my implementation thanks.
Is this book still relevant for my implementation ?
