c476954eef 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`.

5585f9823f chore: cleaner structure/class syntax 
@Kha I implemented the syntax for structure/class that we discussed this morning.
It is much cleaner. See new tests at `struct2.lean`.
I updated the documentation to use it.

5884b9c19a feat: add support for instance ... where 
@Kha The fields are not mutually recursive yet, but it is good enough
 for writing examples in the manual.

See new test

ac85650e0a feat: add optional where clause at declarations 
closes #191

@Kha Note that it expands into a "let rec".
There are many other places where an optional `where`-clause is
useful. We can add them later. It is relatively easy to add support in
other places using the new helper functions
`expandWhereDeclsOpt` and `expandMatchAltsWhereDecls`

0fcf6217ec feat: optional := before constructors in the inductive command 
@Kha In the documentation, I will always use `:=`. The idea is to
avoid the issue: why does `structure` have a `:=` but `inductive`
doesn't.

360fa1638f chore: rename Parser.try to Parser.atomic
