Changing Convention for Giving Explicit Names for a Property.

[vivekjoshi556]

Current Behavior:
Right now, the Validator checks for whether the last rule is a valid rule or not. If it is it interprets it as a rule otherwise it is considered as a name to be used that while displaying error message. But in some cases (such as typos) the last value might be considered as a name even though it was intended as a rule.

Intended Behavior:
If the last value was intended as a rule but was not a valid rule, then it should throw error. And should be used as a name when intended.

Suggested Solution:
If the user wants the last value to be considered as a name, then maybe prefix it with an underscore (_) or something and then during printing the underscore can be removed.
