Hi all,

Running python 2.5, i experience a strange behaviour with the
following code:import imputil

def handle_pye(fullpath, fileinfo, name):
    # Print a debugging message
    print 'Importing "%s" from "%s"' % (name,fullpath)
    data = open(fullpath).read()
    return 0, compile(data,fullpath,'exec'),{}

im = imputil.ImportManager()
im.add_suffix('.pye',handle_pye)
im.install()  # THIS SEEMS TO DO WEIRD THINGS TO SUBSEQUENT
IMPORTS !!!!

import functools

I then get the following traceback:
Traceback (most recent call last):
  File "D:\deleteme\New1.py", line 12, in <module>
    import functools
  File "C:\Python25\lib\imputil.py", line 103, in _import_hook
    top_module = self._import_top_module(parts[0])
  File "C:\Python25\lib\imputil.py", line 190, in _import_top_module
    module = self.fs_imp.import_from_dir(item, name)
  File "C:\Python25\lib\imputil.py", line 545, in import_from_dir
    return self._process_result(result, fqname)
  File "C:\Python25\lib\imputil.py", line 304, in _process_result
    exec code in module.__dict__
  File "C:\Python25\lib\functools.py", line 10, in <module>
    from _functools import partial
  File "C:\Python25\lib\imputil.py", line 106, in _import_hook
    raise ImportError, 'No module named ' + fqname
ImportError: No module named _functools


The mere fact of installing a custom importer seems to break the
import functionality.
