fix typechecker loop when coercing boxes
...
closes #38
2024-02-10 10:07:06 +01:00
03c197bd04
add local bindings to context
...
- without this, inside the body of `let x = e in …`, the typechecker
would forget that `x = e`
- now bound variables can reduce, if they have a definition, so RedexTest
needs to take the context too
