Built in TypeScript; types are included.
Error subclass whose instances get humanized stack traces. Use with new only.
`ts
import { Herror } from 'herro';
throw new Herror('something broke');
`
When flag is truthy or omitted, all stack traces (including plain Error) use the humanized format. When flag is false, restores the default format.
`ts
import { global } from 'herro';
global(); // enable humanized stacks globally
global(false); // revert to default format
`
