Parser enum bug

[tomas99batista]

When parsing enum values the parser has a greedy approach, resulting in an error.

I have an enum

enum Operator {
  o EQUAL // Equal
  o NOT_EQUAL // Not Equal
  o GREATER // Greater
  o GREATER_EQUAL // Greater or Equal
  o LESS // Less
  o LESS_EQUAL // Less or Equal
}

and when using the values on the markdown text I can't use the values GREATER_EQUAL and LESS_EQUAL . All the other values are okay and even this last 2 are ok when using them inside an emit on the logic.

9:46:15 AM - error: Parse error at line 20 column 109
2. "response_time" : "http://www.provider.com/metrics/response-time" - "milliseconds" ("80"). Operator: LESS_EQUAL, tolerance: "15", consequence: "Extra credit at the end of the billing cycle".
                                                                                                            ^^^^^^^^^^^^^
Expected: ', tolerance: '

Expected Behavior

It should parse GREATER_EQUAL and not interpret that is a GREATER and _EQUAL is some additional text that should not be there.
