F# running on the Espruino

Do you want and have plans for supporting the "window" object?

Not really - it's not exactly a JS 'standard', and it makes very little sense on an embedded device that doesn't have windows :) For instance node.js doesn't have a window object either, it has something called global.

global is something I'd like to add though, but as you noted it's very easy to fake it var global = this; at the start of the program.

works with window = this;, but not with replace window.

Not sure I understand the problem? Can you give an example of what doesn't work?
