 Fixed more issues, started processing stuff, we need real example code.
 
+Need to sort out eval. Currently List doesn't get substituted. We should make sure we're CBV. I guess I could always subst (or glue?) since we're head normal form. We need actual values (∏) for checking.
+
+ok, our kovacs eval puts the arg in the environment and continues. So CBN, but maybe duplicate work (for our version).
+
+So smalltt has TopVar with a Level. typechecking binders end up as top too.
+
+Also delayed unfolded values for top or solved metas. This looks like glue - all the bits for the top and a cached value (it's keeping top as values).

+- [ ] Error object like pi-forall
+- [ ] Get implicits working
+- [x] Replace on define
+- [x] more sugar on lambdas
