I am not entirely sure what the intent was for that keyword, but
nothing really matched between the parser, the formatter and the uplc
code gen. I don't think there's any need for a keyword here, trace is
already readily available from the builtins.
This is the most intuitive thing I could come up with: since the
problem is mainly due to the order in which we try declaring the
aliases, then it suffices to simply try as much as we can, and retry
on failure until there's no more failure.
Note that it's important to detect cycles if we do such thing (which
we can by noticing that a given iteration didn't make any progress).
It works pretty well in the end and even allow us to define a new kind
of type error should there be a cyclic definition.
- [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).
Was introduced as a work-around to get some debugging info out of scripts, but tests do now provide the same capability with a better output and, do so automatically.
Pretty useful for debbugging. Though, on second-thoughts, this is
something we may want to review later and maybe have that done by
default for tests.
At the moment, we expects tests to unify to `bool`, and treat `false`
values as failing tests. Yet, on failures, this gives little
information about what's wrong with the test.
It'd be nice to either have better way to assert in tests, or, to
simply accept non-bool tests, and show whatever the test evaluates
to as a debug output.
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 {
```
