5e66f4c97c feat: dot completion experiment
We still need to use the expected type, fix error recovery, etc. But it
is showing signs of life for very basic examples.

It is disabled for now.

2837873db5 fix: longestMatch error recovery
@kha When replacing an error with a longer one, we were keeping the
message for the longer error, but losing its node.

2fc775954c fix: error recovery
@kha We have a few parsers that invoke `tokenFn`, and return error
depending of what is on the top of the stack (e.g., `ident`).
These parsers were not restoring the stack size when reporting errord,
and messing up the error recovery. We never notice the problem because
operators such as <|> restore the stack size, and we were not trying
to elaborate syntacticly incorrect terms.

05022cc80b fix: disable implicit lambda insertion at _, ?h, and by ...
@Kha This commit addresses an issue reported by Kevin. Holes and tactic
blocks represent a discontinuity in the elaboration process.
By introducing inaccessible variables (or "things" as Kevin calls
them), we create error message that are harder to understand (see
affected test), and goals where we didn't allow the user to select the
variable name and/or eagerly unfolded a definition.

BTW, I first considered using "reducible" setting when deciding
whether to insert implicit lambdas or not. This is a bad idea.
See `monotone.lean` test. The decision should not depend on
reducibility status, but whether there is "discontinuity" on the
elaboration process or not. As Kevin pointed out,
"introducing implicits work great if you finish the job".

5ac7b1232a chore: add workarounds
@Kha It seems the recent parser modifications created some unexpected
problems. I didn't investigate them. I am "lost" in the elaborator and
dependent pattern matching land.

1) We can't write anymore
```
f [1, 2, 3] |>.run' 0 = Except.ok ()
```
We have to use parentheses and the error message is weird :(
```
(f [1, 2, 3] |>.run' 0) = Except.ok ()
```

2) I had to add comments to `macro.lean`, I didn't find a workaround
for one of the rules. BTW, I had to add a bunch of `:term` for fixing
the other rules, and the error messages were counterintuitive.
