9538772c1c chore: do not use string interpolation by default at dbgTrace!
It is nice to be able to write `dbgTrace! x` instead of `dbgTrace! "{x}"`

0b81ffb569 refactor: factor out nested do term support and document code
We currently use the nested `do` terms for two combinators: `catch`
and `finally`. We may want to support more in the future.

8a6cb1842f feat: expand doTry
@Kha I did not implement support for reassignments and `continue`,
`break`, `return` inside the `finally` clause. It is doable, but it
feels like unnecessary complexity. We currently don't have any
instance in our code base where this would be useful.

d9d8e95987 feat: elaborate doElems at doLetArrow
@Kha The Rust `let+return` example works in Lean too :)
The Rust function
```rust
fn f (x : i32) -> i32 {
    let y = if x == 0 { println!("x is zero"); return 100 } else { x + 1 };
    println!("y: {}", y)
    y
}
```
The Lean version is
```lean
def f (x : Nat) : IO Nat := do
let y ← if x == 0 then IO.println "x is zero"; return 100 else pure (x + 1)
IO.println ("y: " ++ toString y)
return y
```

The main missing feature now is the `try-catch-finally` `do` element.

5b76155318 feat: new return semantics
`return e` is not equivalent to `pure e` anymore.
Now, `return e` means "return value `e` as the result of the root `do` block".

Local name resolution was incorrect when identifier had macro scopes
and projections were used.

98dbe45ab8 chore: remove Monad List instance
@Kha The new `do` notation works for pure code too.
It automatically inserts `Id` if the expected type is not a monad.
This works great when we are not conflating data and control.
After deleting `Monad List`, we will be able to write functions such as
```lean
def mapWhen (p : Nat → Bool) (f : Nat → Nat) (xs : List Nat) : List Nat := do
for x in xs do
  if p x then
    x := f x
```
without adding `Id.run` before the `do`.
