help: Did you forget to import it?
Data-type constructors are not automatically imported, even if their type is
imported. So, if a module `aiken/pet` defines the following type:
┍━ aiken/pet.ak ━━━━━━━━
│ pub type Pet {
│ Cat
│ Dog
│ }
You must import its constructors explicitly to use them, or prefix them
with the module's name.
┍━ foo.ak ━━━━━━━━
│ use aiken/pet.{Pet, Dog}
│
│ fn foo(pet : Pet) {
│ when pet is {
│ pet.Cat -> // ...
│ Dog -> // ...
│ }
│ }
```

$ cargo install --git https://github.com/aiken-lang/aiken.git
$ aiken --help
How to use
For more information please see the user manual.
Roadmap
Aiken defines its roadmap using Github Milestones. The roadmap isn't set in stone, but gives a high-level overview of where the project is headed for.
