Schemas with dotted variables

FormEncode schemas seem like a good way to validate other kinds of
data besides form input, in particular a Pylons configuration from an
INI file.  However, the schema format does not allow variables with
dots in their names, which is common in this situation.

I wonder if a small enhancement would alleviate this, such as treating
a double underscore in the middle of a name as a dot.

    class ConfigValidator(Schema):
        beaker__cache_time = Integer()    #  =>   {'beaker.cache_time': 3600}

Or the schema class could have a dict attribute of validators to merge in:

    class ConfigValidator(Schema):
        other_validators = {
            "beaker.cache_time":  Integer(),
            }
