<Can> without subject

I have a flat component permission-wise, I do not really use the “of” -part (or subject) of the <Can> component. Casl seems to work fine with me leaving it out but the React component gives prop type warnings. I have worked around this by creating a custom can-component but I’m wondering if the prop-type validation could be loosened or if there is a more elegant way handling cases like: <Can I="post" />

Tasks:

• update types for ForbiddenError.throwUnlessCan
• update types for can, cannot, relevantRuleFor, rulesFor, possibleRulesForofAbility`
• update types for can & cannot of AbilityBuilder
• casl/angular
• casl/aurelia
• casl/vue
• casl/react
• add tests for casl/ability

After some thinking about this, I realised that on @casl/ability level it can be implemented without changes. The only thing which you need to do is to define custom subjectName function:

const subjectName = () => 'all'

const ability = AbilityBuilder.define({ subjectName }, (can) => {
  can('read')
  can('think')
})

console.log(ability.can('think')) // true
console.log(ability.can('write')) // false

The only thing which needs to be changed is Typescript declarations and complementary packages
