Subject: Partially revert "remove mechanism for specifying superclass in _constructor_maker_for"
X-Git-Tag: v1.003001~15
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=gitmo%2FMoo.git;a=commitdiff_plain;h=4ae155a9c590216ff7ac2965b3956079574c0e97

Partially revert "remove mechanism for specifying superclass in _constructor_maker_for"

This partially reverts commit 8dee08c10f9b63372dff89d38b37b175cdda4489.

Re-add the mechanism for specifying superclass, but only use it when we
know it is accurate.
