It's not really faster if you only use the interface irregularly and so 
have to look up how to spell "bar" every time whereas your IDE will 
tell you about Foo.BAR.

Well I found it a problem for <canvas> context names at least. Again, 
if you use it all the time it isn't a problem but in that case I didn't 
and there wasn't sufficient precedent to establish a 
lowercase-always-everywhere rule.

Anyway possibly I am starting to sound like someone who cares. I'm not 
sure that I am.
