Dynamically invoke Rez.Layouts.xxx?

I want to eliminate "if ... then" chains for snippet like:

        if(I2TinC){ 
            setLayout(Rez.Layouts.WatchFaceI2(cdc));
        }else{       
            setLayout(Rez.Layouts.WatchFace(cdc));
        }

is it any way to do something like

var layoutMethod = Rez.Layouts.WatchFaceI2;

setLayout(layoutMethod.invoke(dc));

Any help please!

You can create a Method object and call invoke on it.

var layoutMethod = new Method(Rez.Layouts, :WatchFaceI2);
setLayout(layoutMethod.invoke(dc));

This breaks now after connectiq-sdk-lin-7.1.0_RC2-2024-02-14-4a71df847/ because of the change as described by the introduction of SDK 7 where resources are now Toybox.Lang.ResourceID's.

It now yields…

Thank you so much! It works!
I didn't realise need to use Symbol instead of just function call.

It now yields the following error:

// ERROR: fenix6xpro: /home/ciq/barrels/OPN/source/X11/ViewX.mc:122,12: 
// Undefined symbol ':Layouts' detected.

// which is this bit of code:
if (self._layout != null) {
    var m = new Lang.Method(Rez.Layouts, self._layout);
    setLayout(m.invoke(dc));
}
