Trivial proposal.

Now Ractor#[]/#[]= is supported to access current ractor local storage. However, it doesn't allow to access local storage of other ractors.

Ractor.current[:foo] = 1

Ractor.new{ 
  p Ractor.main[:foo] #=> nil
}.take

So providing Ractor.[]/[]= is more reasonable.
Further more, we don't need to use Ractor#current and it is slightly faster.

+1, makes perfect sense (IMO it would be nice to do the same for Fiber and Thread as well but out of scope of this issue).

it would be nice to do the same for Fiber and Thread as well

Would also be the occasion for Thread[] to be actual thread local instead of fiber local.

I'd expect that accessing other Ractors' local storages will raise an exception.

Ractor.[] and Ractor.[]=

Ractor#[]/[]= is only for accessors to the current ractor, so that
Ractor.[]/[]= is simpler.
