Summary:
The OCL expression syntax is difficult to extend for other purposes. The @pre postcondition operator, and the ,^,? tokens are examples of extension of the core syntax.
Perhaps @pre could be generalized as an instance of an @token
{....}suffix which could be parsed as an AnnotationExp for tooling to ignore but support extension for.
Can more arbitrary punctuation such as ,^,?,#,% be generalized?
