[SOLVED] JSON attribute accepts spaces in name but cannot be addressed

Hi,
I just came over a an odd situation:
I have a structure myData

var myData={
  'A1':{name:'..'},
  'A2':{name:'..'},
  'A 3':{name:'..'}
};

I can call myData.A1 as well as myData.A2 but of course myData.A 3 fails because of the space.
Is it possible that Espruino interpreter should reject attributes containing spaces in the name?
