Feature Spec
Assuming we have an optional Map, and we want to access one of its properties,
optional_map.get("property") (or even optional_map?.get("property")) will throw the following error: "property access unsupported on type Map?"
this error message might not be clear enough to guide the user on how to fix the error.
(At the end I solved it this way:
let m = optional_map ?? {property: "x"};
m.get("property");
)
Use Cases
accessing a property on an optional map
Implementation Notes
We will also support optional_map?.property in the future
