feat: heterogeneous OrElse and AndThen
...
@Kha I had a few issues similar to the `Append` issues.
We used a similar idiom for writing builtin parsers where we may write
```
def p : Parser := "foo " >> "bla "
```
as a shorthand for
```
def p : Parser := symbol "foo " >> symbol "bla "
```
I want to support `builtin syntax` one day :)
That being said, we should decide whether we keep `HAppend`, `HOrElse`,
and `HAndThen` or not.
The only one I wish I had in the past is `HAndThen`.

fix: doLetArrow and doReassignArrow
...
@Kha the new tests did not work without this fix.
The `| _ =>` was being parsed as part of the `doLetArrow` and `doReassignArrow`

@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.
