I know how to use it to create the query, but that's it. And even then, I
can only do basic query, as I don't know where to find documentation on the
specifics.
It's possible to use for "dematching"? The ideal would be to select all
catch statements that are not const&, but there are no example anywhere on
that kind of selection.
