bug: method() and new Method() issues. Cannot find symbol ':method' on type 'self'

import Toybox.Lang;
import Toybox.Position;

function onPosition(info as Position.Info) as Void {
    // log("onPosition");
}

function initLocationEvents1(config as Number) as Void {
    Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, method(:onPosition));
}

// (:typecheck(false))
function initLocationEvents2(config as Number) as Void {
    Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, new Method($, :onPosition));
}

In the 1st case I get:

Cannot find symbol ':method' on type 'self'

It looks like method() only works in classes? I'm not sure why, this really should work, but at least it should be documented.

In the 2nd case I get:

Passing '$.Toybox.Lang.Method' as parameter 2 of poly type 'PolyType<Null or ($.Toybox.Lang.Method(loc as $.Toybox.Position.Info) as Void)>'.

This at least can be worked around by adding the typecheck false annotation (or new Method($, :onPosition2) as Method(loc as Position.Info) as Void), but I feel like this shouldn't be needed,  method() and the compiler should be clever enough to work it out.

SDK 8.1.0, typecheck:3, I tried it on fr955 in the simulator
