Hi,

Thank you for doing this work! Super excited to get my hands on it once it's ready :)

Just noticed the title says without auto accessor. Wonder what this means for a use case like this (as mentioned in the proposal):

class Example {
  @reactive accessor myBool = false;
}

As far as I understand, this should still be possible without the accessor keyword, except the decorator function will have to define its own getter and setter, so pretty inconsequential that it's going to be missing, right?

Yes, I'll work on auto accessor part in the future with another PR
