Sorbet's runtime type checking component

Type checking and type casting of parameters for Action Pack

Makes sure users don't accidentally create an account for the wrong e-mail address. Because 'gmial' isn't actually what they meant to type. Similarly, 'yaho.com', or the strange-but-true '.c0m'. Not even making that one up. If you're concerned about false-positives, it's super-easy to check. Ther...

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

Pronto runner for flow, a static type checker for javascript.

All the flexibility of a Ruby Struct, but with type checking on its properties. Also benefit from being able to define complex types using RBS type notation.
