------------------------------------

You can write an email in a string, e.g.

person {

>                 URL: https://issues.apache.org/jira/browse/GROOVY-8626
>             Project: Groovy
>          Issue Type: New Feature
>          Components: Compiler
>    Affects Versions: 2.5.0
>            Reporter: Alexander Klein
>            Priority: Major
>              Labels: compiler, dsl, lexer
>
> 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.
