Description

For writing DSL's it would be helpful to use the @ sign standalone as a custom Operator implemented by custom AST transformations.

As well it would be great to be possible to write eg. email addresses without quotes to be picked up by an AST transformation.

This requires @ as a single char and @ not at the beginning - to prevent problems with annotation literals.
