Does not actually work, undefined is used in some places as a
stopgap measure.

Switch more files over to new Expressions
2013-07-04 17:31:22 +02:00
Evan Czaplicki
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.

Turn off debug code that printed all constraints during unify.
...
This debug code is very noisy and makes it hard to test the dev
branch because you can't see warnings buried in all the debug
output.
