Yes I saw your tweet and it's already on my to do list for this evening.
Except our attempts to extend L.Bounds and L.LatLngBounds fails as those no longer inherit from L.Class so don't have an include method...
I'll try and refrain from any "told you so comments" about the wisdom of monkeying with the internals of third party code ;-)
Pushed as 6bde69a but not yet deployed. It will be up on http://master.apis.dev.openstreetmap.org/ shortly for testing before I push it live.
Nice, looks like you fixed #190 too. Point taken on the monkey patching. :)
Well nobody seems to have spotted anything, so I pushed this live.
