I want the function and its args to be as natural as possible. So
you'd pass that as:
some_fun :location => {:city... etc
and then use it as location[:city][:population], just as you would if
you'd passed a hash to any regular function. If you want to do what
you're proposing, you can still extend Hash accordingly.
I'm trying to make it as simple as I can to write functions that take
arguments by name, with meta-information and attendant behavior
happening automatically, such as which ones are required, have default
values etc. I don't want to do any more than that.
