Some Lua APIs provide objects with methods that must be invoked using dot syntax (thing.method(...)) as opposed to colon syntax (thing:method(...)). Having a custom decorator for this would be very useful.

Edit: This behavior already exists for namespaces, it just needs to be expanded for object-oriented use. I propose a new custom decorator, !DotMethod, applicable to declarations of classes, interfaces, type literals, and methods of any of these.

Example usages:

/** !DotMethod */
declare class SomethingExternal {
	doThing(): SomethingReturned;
}

/** !DotMethod */
interface SomethingReturned {
	doOtherThing(): void;
}

type SomethingElse = {
	/** !DotMethod **/
	dotMethod(): void,
	regularMethod(): void
}
