And disable multi-patterns clauses. I was originally just controlling
whether we did disable that from the parser but then I figured we
could actually support multi-patterns clauses quite easily by simply
desugaring a multi-pattern into multiple clauses.
This is only a syntactic sugar, which means that the cost of writing
that on-chain is as expensive as writing the fully expanded form; yet
it seems like a useful shorthand; especially for short clause
expressions.
This commit however disables multi-pattern when clauses, which we do
not support in the code-generation. Instead, one pattern on tuples for
that.
Isolated doc comments causes the compiler to panic with:
```
'no consecutive empty lines'
```
This is reproducible when doc comments are wrapped in sandwich between
comments and newlines.
The typed-AST produced as a result of type-checking the program will
no longer contain unused let-bindings. They still raise warnings in
the code so that developers are aware that they are being ignore.
This is mainly done to prevent mistakes for people coming from an
imperative background who may think that things like:
```
let _ = foo(...)
```
should have some side-effects. It does not, and it's similar to
assigned variables that are never used / evaluated. We now properly
strip those elements from the AST when encountered and raise proper
warnings, even for discarded values.
It's generally a bad idea to use equality on enum variants because this won't trigger any compiler errors in the future yet could have hazardous effects if adding new variants. So it's usually preferrable to use exauhstive pattern matching and let the compiler warn missing cases in places where it matters.
This leads to more consistent formatting across entire Aiken programs.
Before that commit, only long expressions would be formatted on a
newline, causing non-consistent formatting and additional reading
barrier when looking at source code.
Programs also now take more vertical space, which is better for more
friendly diffing in version control systems (especially git).
It is now possible to leave a hole in a type annotation and have the compiler fill-in the expected type of us.
This is a pretty useful debugging tool when playing with complex functions.
