Re: Lazy import of modules


The lazy loading in common seems fine minus one small issue.  If I read it correctly It looks like it is limited to a class or module.   There doesn't seem to be a way to proxy into an object itself.  I'd like to be able to specify a class (or a method) and have it lazy loaded into an object backend.  This is what import_object did automatically that makes it so versatile.  Admittedly it had an annoying bug that ate underlying exceptions, but imo, that is a bug that can be addressed.
