It would definitely solve my recursive file selection, except for the
exclusion, but for that you could use another operator ('-' ?).

FILES= `tree("www") - tree("CVS") - tree("*.bak")`

But then we have another problem, what is meant by *.bak? Just the .bak files
in the current directory, or everything that end in .bak ?
I would suggest calling tree something like rglob (recursive glob), if its
arguments are going to include wildcards.
Too bad that the - operator is not defined for lists in Python, but we can
probably overload it.

The rglob/tree function definitely is useful, I think.
