Unlike when using sets for a similar effect, the original ordering of the
items in the collection is preserved by this function.

[1, 2, 3, 4]
>>> print list(distinct('foobar'))

This function is similar to what is provided by the ``fnmatch`` module in
the Python standard library, but:
* can match complete (relative or absolute) path names, and not just file
names, and
* also supports a convenience pattern ("**") to match files at any
directory level.
Examples:
>>> pathmatch('**.py', 'bar.py')
True
>>> pathmatch('**.py', 'foo/bar/baz.py')
True
>>> pathmatch('**.py', 'templates/index.html')
False
>>> pathmatch('**/templates/*.html', 'templates/index.html')
True
>>> pathmatch('**/templates/*.html', 'templates/foo/bar.html')
False
:param pattern: the glob pattern
:param filename: the path name of the file to match against
:return: `True` if the path name matches the pattern, `False` otherwise
