$mwEmbedContainer could work. I guess this is pretty minor now that I better understand what Pimple is doing....

What I don't understand is why use a framework like pimple if it does not handle autoLoading? .. we are forced to load every class it ~may~ use .. with a central class handler like this you would expect it to only load what you use, not have to predefine array names ahead of time. 

I don't think this is a deal breaker for our use case, since we don't have ~that~ much php being run even if we load everything, but still odd that this mini-framework does not handle that.
