By "special things" you don't mean that walk() is suppose to skip over
aliases, do you?  Because as it is right now, aliases are walked.  And if
they are walked they can lead to two problems:

1) an infinite loop between two folders
2) bad pathnames being passed to the walkfunc (which is the issue that
resolve() was written to address).

If these undesirable behaviors were deemed bugs then the macpath.walk()
function could just be modified.  I have attached a version which has the
same behavior as the original but now has 3 optional arguments to handle
walking aliases, other volumes, and a dictionary to prevent walking
previously walked folders.

Also, I made the modification to islink() so it would return a 1 if a file
is an alias and 0 if it is not (or if it can't be resolved, perhaps
because someone else's walk gave it a path with multiple aliases in it, in
which case the resolve function that you have could be used by that person
to demangle the path first).
