Convert more files to the new Expression format that relies more on
...
patterns. Seems to clean things up so far.
Also, begin adding a module that resorts definitions to make sure
that each definition comes after the ones it depends on. This will
also make it possible to disallow recursive values statically.

...
pulls the arguments out of Definitions (placing them in lambdas).
