[Feature Request] Having a typeof operator in Winglang

[harsh9607]

Feature Spec

I was wondering if we could have a typeofOperator like we have in javascript. We could have something like

let x  = 42 ;
log( typeof(x));

returns number;

Use Cases

https://www.winglang.io/docs/language-reference

It is part of Roadmap

Reflection: add an extended typeof operator to get type information.

Implementation Notes

It could be built upon the typeof operator of Javascript.

@MarkMcCulloh, @tsuf239, @hasanaburayyan, @Chriscbr - would you suggest implementing this similar to:

1. util.sleep()
2. Our built-in log()
3. Any other suggestion on how to implement this?

I am not sure we want to implement this without a broader discussion of reflection and also typeof in javascript is not compatible with strongly typed languages... (where the typeof bucket could be cloud.Bucket or maybe some IBucket - thanks @Chriscbr )

[hasanaburayyan]

Yea I think for sure its something that would be useful to have and we probably want it. However, its kinda complicated because of the way typeof works in javascript. Maybe we add this to an upcoming team time discussion? Im not sure how exactly implementation would work, somehow we need to map the javascript back to the Wing type.

Makes sense - I'll add to a next team time so we can discuss it. Marking this issue p3 in the meantime.

@ainvoner After re-reading this issue, if I understand it correctly this might be a separate feature from the typeof type operator that TypeScript introduces for use inside type annotations and type parameters (e.g. someFunc<typeof otherFunc>()). Their docs explains it better than I can https://www.typescriptlang.org/docs/handbook/2/typeof-types.html
