Some notices about code:
1 Near function transformOperator() there is wrong operator name "@<"
2 int_query (and intquery) should be replaced to query_int to be consistent with
actual type name. At least where it's used as separate lexeme.
3 For historical reasons @@ doesn't commutate with itself, it has a commutator
~~. Patch assumes that @@ is self-commutator, but ~~ will use 'contsel' as a
restrict estimation. Suppose, we need to declare ~~ as deprecated and introduce
commutating @@ operator.
