Never type
Syntax
NeverType :!
The never type ! is a type with no values, representing the result of
computations that never complete. Expressions of type ! can be coerced into
any other type.
For now, this reference is a best-effort document. We strive for validity and completeness, but are not yet there. In the future, the docs and lang teams will work together to figure out how best to do this. Until then, this is a best-effort attempt. If you find something wrong or missing, file an issue or send in a pull request.
