Adding slots without block argument reference

[andreasgerner]

Currently, slots are added in the following way (example written in haml):

= render ExampleComponent.new do |comp|
  - comp.slot(someProp: "a")
  - comp.slot(someProp: "b")

IMO, I'd would be nice to somehow also implement this without needed to call slot on comp everytime, like:

= render ExampleComponent.new do
  - slot(someProp: "a")
  - slot(someProp: "b")

Is there somehow a way of achieving this behavior with the current implantation?

I guess the aim here would be for the block passed to render to be executed in the context of comp rather than whatever self usually is inside that block (presumably the ActionView::Base instance that's being used to render). component.instance_eval(&block) rather than straight-up yield, for the sake of argument. It's a nice idea and I can see why it'd be useful. This change most likely wouldn't be dangerous when it comes to evaluating helpers within this context - they're also callable via helpers on component instances themselves, so that would be workable.

I'd be open to seeing it implemented. The render method might need monkey-patching in order for it to work.

@boardfish is right that we'd probably need to change the receiver of the block, which I think would be more trouble than it's worth.
