It is nice to be able to write `dbgTrace! x` instead of `dbgTrace! "{x}"`

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.

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.

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.

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".
