Enums, properties, generics, structured objects and runtime type checking.

Check yardoc format like tag type.

Composable type-safety checks

The Preconditions library provides a simple set of methods for checking arguments being passed into a method. Instead of writing custom checks and raising exceptions directly in your code you can use Preconditions to verify basic properties of your arguments (not-nil, satisfying a boolean expres...

A type coercion lib works with Sorbet's static type checker and type definitions; raises an error if the coercion fails.

RubyLess is an interpreter for "safe ruby". The idea is to transform some "unsafe" ruby code into safe, type checked ruby, eventually rewriting some variables or methods.
