Is it planed to have Spread syntax (...) ? No, use arguments instead

It has been asked before, but it's not high up my priority list as I feel like it doesn't actually add much, and might be a pain to implement.

JS has a built-in arguments variable:

var logger = function(){
      console.log.apply(null, arguments);
} 

should work on Espruino just fine - no need for spread at all :)
