I remember this notion when most of the features were on a wishlist and a roadmap, but why its still a vaporware?

Spouting V is vaporware, is nonsense. Especially when they have an update at around a new one per week and over 90 releases- https://github.com/vlang/v/releases

Yeah... 13,000+ git commits. Certainly vaporware. Come on man.

Yeah, it doesn't change the fact that their advertised features don't work as expected and is crippled with tons of bugs.
