def expr_match(line, expr):
    '''
    Checks whether or not the passed value matches the specified expression.
    Tries to match expr first as a glob using fnmatch.fnmatch(), and then tries
    to match expr as a regular expression. Originally designed to match minion
    IDs for whitelists/blacklists.

    Note that this also does exact matches, as fnmatch.fnmatch() will return
    ``True`` when no glob characters are used and the string is an exact match:

    .. code-block:: python

        >>> fnmatch.fnmatch('foo', 'foo')
        True
