WebDSL’s HQL syntax does not allow escapes in the limit part of an HQL query. Following is syntactically invalid, yet seems ok to me:

from Issue as i left join i.tags as t
where (t in i.tags) and (t._project = ~this)
group by t
order by count(i) desc
limit ~maximumNumberOfTags; // Syntax error: ~ not expected
