I figure you mean

{ 'enum': 'Foo', 'data': [ 'bar' ], }
{ 'enum': 'Gur', 'data': [ 'ble', ] }

My parser rejects both:

<stdin>:1:37: Expected string
<stdin>:2:35: Expected "{", "[" or string

I commented out the first to get the second error.  Making the parser
continue after errors didn't seem to be worthwhile.

Indeed.
