Details:

here is an example:

octave:1> eval('[{"value":"New","onclick":"CreateNewDoc"}]')
ans = 
{
  [1,1] = 
  [1,2] = 
}

I was expecting eval fails and throws an exception.

Some more strange results:

octave:5> eval('[{"test"}]')
ans = 
{
  [1,1] = test
}


octave:7> eval('[{"test":"t"}]')
ans = 
{
  [1,1] = t
}

octave:8> eval('[{"test":"aaa"}]')
ans = 
{
  [1,1] = 
}

octave:10>  eval('[{"test":"ttt"}]')
ans = 
{
  [1,1] = t
}


I don't really understand the rationale behind this. I discovered this issue
as I am working on a JSON encoder/decoder for MATLAB/Octave, see
