Note: the problem is only present when importing a builtin explicitly.
When using a qualified import, it compiles fine.

This is an example of output from the formatter now:
```
//// Some module documentation
// foo
const a: Int = 42
// Some comment block
// For which newlines are respected.
// Foo
// Another one
/// add_one documentation
pub fn add_one(n: Int) -> Int {
// n + 1
n + 1
}
```
before this commit, comments would all be collapsed into one group
above the function as:
```
// Some comment block
// For which newlines are respected.
// Foo
// Another one
/// add_one documentation
pub fn add_one(n: Int) -> Int {
```
To be more progressive in introducing concepts. It also now groups similar concepts together so that they are easier to find and connect with one another.
I've also added few precisions along the way, as well as corrected a few old syntax (e.g. 'case', generics, tuples..).
Note that some examples provided in the language tour currently fail to parse / type-check properly.a
