Sorry for the confusion. I did not mean that "&" should be mandatory,
just that "&" might make it easier to avoid a need to escape things. So,
it could be used _instead_ of escaping.

But at this point you are more familiar with that parser than I am, so
my idea does not seem to be viable.

Backward compatibility will be easy - just leave the current code when
old query version is detected. We should better focus on the new syntax
in future and leave the current syntax as compatibility layer that will
be eventually deprecated.
