I'm not a big fan of the sequence-or-callable argument. Why not just make it a callable argument, and supply a utility function so that you can write something like:: excludefunc = shutil.excludingpatterns('*.tmp', 'testdir2') shutil.copytree(srcdir, dstdir, exclude=excludefunc) ?

I made another draft based on a single callable argument to try out: http://bugs.python.org/file10073/shutil.copytree.filtering.patch

The callable takes the src directory + its content as a list, and returns filter eligible for exclusion

That makes me wonder, like Alexander said on the bug tracker: In the glob-style patterns callable, do we want to deal with absolute paths ?
