Interpolation is working - there is a bug in your logic :-D

Your string containing the interpolation value is :

    string(default="fuzzy-%(man)s")

You have defined 'man' in your DEFAULT section to be :

    string(default="man")

So ConfigObj replaces ``%(man)s`` with ``string(default="man")``. The
result is :

       fuzzy-string(default="man")

Try replacing the line in your DEFAULT section with :

    man = wuzzy

That should do something a bit more expected. :-)

*However* - that will then raise an error because the default section
doesn't contain a valid check.

Your code will still print "validation succeeded" - because check is now
a dictionary, which doesn't evaluate to False.

    if check:
       print '*** validation succeeded ***'

Should be changed to :

    if check == True::
       print '*** validation succeeded ***'

The answer is for validation to *not* be done on the 'DEFAULT' section.

I'm targeting all the discussed recent changes/bugfixes for a 4.1.0 release.

All the best,
