why i don't like os.walk()

[Skaperen]

i have decided that i don't like os.walk(). that means i will be looking to code my own file tree recursion generator. the biggest reason is that i find no means to modify the list of subdirectories that it uses to descend down to the next level, such as sorting them or removing selected subdirectories or deciding which ones are allowed to follow symlinks or descend into a different filesystem or owner space. i have already written this kind of thing in C (where existing tools were similarly limited) so the logic should be easy enough for me to do. fyi, my C recursion code even includes the ability to yield directories when ascending back up to them (e.g when all the descents are complete). this should be even easier in Python than in C since Python already has the means to do generators (which my C code was trying to fake).
