> Issue Type: Improvement
> Affects Versions: 3.1
> Reporter: Dmitri Blinov

>
> It's not possible to parse scripts like
> {code:java}
> x.size(0){code}
> or
> {code:java}
> x.empty(0){code}
> because of current syntax restrictions.
> {{empty}} and {{size}} are perfectly valid method identifiers in java, and though uncommon, can be declared with arguments. As of now Jexl allows only to call parameterless {{empty()}} and {{size()}} methods
