Layout module - BTN2 undefined (?)

Hi Al,
it seems that the Layout module has a problem, perhaps related to new handling of let/const of v14 firmware.
When rendering on a Bangle2 a layout with more than one button, the following message is diplayed:

Uncaught ReferenceError: "BTN2" is not defined
 at line 115 col 79 in Layout
...pressHandler.bind(this,1), BTN2, {repeat:true,edge:-1}));
                              ^
in function "setUI" called from line 65 col 14 in Layout
  this.setUI();
             ^
in function "Layout" called from line 373 col 14 in Layout
], lazy:true});
             ^

This happens even running the sample code available in the tutorial, e.g.:

var Layout = require("Layout");
var layout = new Layout( {
  type:"v", c: [
    {type:"txt", font:"6x8:2", label:"A Test", id:"label" }
  ]
}, {btns:[
  {label:"One", cb: l=>print("One"),  cbl: l=>print("One long press")},
  {label:"Two", cb: l=>print("Two")},
  {label:"Three", cb: l=>print("Three")}
], lazy:true});

function setLabel(x) {
  layout.label.label = x;
  layout.render();
}
g.clear();
layout.render();

I'm pretty sure that it worked on v13.
