how to iterate over an AA by key-value pair (tuple)?

It's probably better to call the method "byPair" that is shorter.

Some people want those pairs to be tuples. But D lacks built-in 
tuples, so you need to use typecons ones. But to use the typecons 
ones you need to import half Phobos. It seems there is no good 
solution.
