5c68f6bb73 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.

69ed7631fe Start switching over to an AST that uses patterns in lambdas and
