I don't like your solution (although it is better than your description of the current use-case). I prefer to use:
onClick (e) { this.doSomething(data) }
Yeah .. it's (the package) totally an opinionated solution, but hey .. why do you prefer imperative than declarative? Just want to hear your opinion, I'm open to any idea.
I would prefer declarative if I didn't need to install a package. Every dependency is a burden.
