- We now consistently desugar an expect in the last position as
`Void`. Regardless of the pattern. Desugaring to a boolean value is
deemed too confusing.
- This commit also removes the desugaring for let-binding. It's only
ever allowed for _expect_ which then behaves like a side effect.
- We also now allow tests to return either `Bool` or `Void`. A test
that returns `Void` is treated the same as a test returning `True`.
This is debatable, but I would argue that it's been sufficiently
annoying for people and such a low-hanging fruit that we ought to do
something about it.
The strategy here is simple: when we find a sequence of expression
that ends with an assignment (let or expect), we can simply desugar it
into two expressions: the assignment followed by either `Void` or a
boolean.
The latter is used when the assignment pattern is itself a boolean;
the next boolean becomes the expected value. The former, `Void`, is
used for everything else. So said differently, any assignment
implicitly _returns Void_, except for boolean which return the actual
patterned bool.

This is useful when splitting module for dependencies, yet without the desire to expose internal constructors and types. This merely skips the documentation generation; but doesn't prevent the hidden module from being accessible.
The idea is pretty simple, we'll just look for lines starting with Markdown heading sections, and render them in the documentation. They appear both in the sidebar, and within the generated docs themselves in between functions. This, coupled with the order preservation of the declaration in a module should make the generated docs significantly more elegant to organize and present.
The rationale is to let them in the order they are defined, so that
library authors have some freedom in how they present information. On
top of that, we'll also now parse specifi comments as section headers
that will be inserted in the sidebar when present.
As well as fixing a couple of other issues thanks to conformance
tests. Some functions like multiply_integer or verify_ed25519_signature
have also slightly changed their costing function.
There were some odd discrepancy for `integerToByteString` on the mem
side. Either 1 or about 1000 mem units off; which I couldn't quite
figure out. Yet, it proves useful to validate builtin at large and
ensure we have a valid cost model for v3.
This covers every proposal procedures but protocol parameters, this
one is yet to be done. It spans over 30+ fields, and felt like it is a
big enough piece to tackle it on its own.
Alongside a bunch of other stuff from the coverage list. In
particular, the mint transaction contains:
- reference inputs
- multiple outputs, with assets, and type-0, type-1 and type-6
addresses.
- an output with a datum hash
- an output with an inline script
- carries an extra datum witness, preimage of the embedded hash
- mint, with 2 policies purposely ordered wrongly, with 1 and 2
assets purposely ordered wrong. One of the mint is actually a
burn (i.e. negative quantity)
