Correct syntax needed for bind() on 'this' object using class

...it looks like hat you have some left-overs in your Espruino...

g is nowhere defined in that snipped, so I expect it came from previous post... but it also could come from some internal that the interpreter looks at, does not find it a bindable, but thinks it is a number.

Doing things in the console without wiping every thing out, creates a lot of confusion.

Again, I feel that Espruino is still playing tricks on you, @Robin... Espruino is a living object,... similar to the DOM of or in a Browser. Most operation on it leave some (big Bear claw) prints behind... to haunt later... Halloween is about to come... So we should get some Espruino driven flashy wearables... what about a contest, @Gordon?
