That’s exactly a point that reached my interest in the given example

My brain looking at this contamination wondering things like:
- Then we would need “await @inject(‘knife’)” ?
- Then we would need “async class Hero {…}” ?
- Then users should take care to do “await new Hero()” ?
- and/or would it mean that we could do instead “class extends Promise { … }" ?

Ok… Are async Classes / Constructors crazy or just natural evolutions we could/should be prepared to see in the future !?

Just wondering, I’m curious, I’d understand either that to be crazy or natural ;-)

Just to be fair, Sync is still appreciated in some situations in JS like
- in Dedicated Workers, 
- in other SSJS platforms like RingoJS, Wakanda, APE, …
- as it is also in Node.js when writing CLI applications (then tricks are occasionaly used in addition to Sync APIs) ;-)
