 - [ ] if we're staying with this version of auto, we might need to list candidates and why they're rejected. e.g. I had a bifunctor fail to solve because the right answer unblocked a Foo vs IO Foo mismatch
 - [ ] literals for double
 - [ ] add default failing case for constructor matching to catch errors
-- [x] Add icit to Lam (see `check` for details)

+- [x] Add icit to Lam
 - [ ] add jump to definition magic to vscode extension
+  - [x] Cheap dump to def - dump context
 - [ ] TCO? Probably needed in browser, since v8 doesn't do it. bun and JavaScriptCore do support it.
 - [x] deconstructing `let` (and do arrows)
 - [x] Fix string printing to be js instead of weird Idris strings
 - [x] make $ special
   - Makes inference easier, cleaner output, and allows `foo $ \ x => ...`
   - remove hack from Elab.infer
-  - [ ] `$` no longer works inside ≡⟨ ⟩ sort out how to support both that and `$ \ x => ...`

 - [ ] rework `unify` case tree
   - Idris needs help with the case tree to keep code size down, do it in stages, one dcon at a time.
   - I'm not sure it can go a few steps deep and have a default hanging off the side, so we may need to put the default case in another function ourselves.
