        Presumably python is showing you the message embedded in the exception
(which is empty ?) or do we miss even that ?

        Quite :-)

        IMHO we need to make that code efficient by having a var-args style
helper:

        throw FooException("Failure loading file '%S' code %d",
                           aOUStr.pData, nCode);

        That would also be fairly code size efficient as well vs. the
heavy-lifting, and big string-buffer construction madness :-)

        Certainly rather an 'advanced' easy hack but worth doing :-) I would be
-extremely- skeptical of putting more data into types.rdb though - that
is still using the hideous 'store' code that everyone should be eager to
see the back of, and which wastes space and I/O left and right like
nobody's business :-) Even after some work to shrink that we have
(commas added to size for effect):

-rw-r--r-- 1 michael users  1,375,023 Nov 16 10:21 offapi.rdb.regview-output.gz

        It'd be great to use a more pleasant format like Stephan's new configmr
XML - if we can get the performance we need there; and of course add the
API docs to some parallel docs file, only loaded when needed
(interactively by developers). But of course it's a good idea.

        ATB,

                Michael.
