Feature: delete keyword proposal

[john-bv]

Delete would remove an object or identifier from memory.
Use case:

const somethingNoLongerUsed: int = 10;

delete somethingNoLongerUsed;

However, this comes with a side effect:

const myObject: Obj = {};
const myReference: Obj = Obj;
delete myObject;
print!(myReference); // Dangling pointer, pointing to unknown reference

I plan on having built in memory safety, similar to rust, but at the compile level. However this is still an issue with delete.
