Hi Tim,

Thanks for your thoughts. I will definitely go over your other email in detail when I have some more
time and energy, and update some of my examples. 

Regarding this point, I think it's a really interesting observation, and I wonder if we should
be looking for different keywords that read more clearly. For instance: 

using(new SomeManager() for $someResource)

using($someResource from new SomeManager())

context(new SomeManager() giving $someResource)
