It's best to keep builtin as-close-as possible to their standard name
because they're hard to document. We can then leverage the prelude and
the standard lib for convenient names.
This is because there's no proper way to catch panics in Rust, which
makes it hard to know _which_ test did cause the panic when this
happen. The stack trace gives little detail about this, but we can
print this information before it happens -- making it easier to
identify the culprit.

- [x] Display function arguments using a newline-multiline strategy
when the signature gets too long. For example:
```
union_with
( left left: AssocList<key, value>
, right right: AssocList<key, value>
, with with: fn(key, value, value) -> value
) -> AssocList<key, value>
```
- [x] Show type-aliases as type-aliases in signatures; provided
they've been specified as type annotations. Otherwise, fallback to
the inferred type.
- [x] Do not show argument names in signatures, but show labels when
they're present. This reflects more the original intent behind
labels (which are meant as public-facing documentation).
