I think this is a bad idea.  

First of all, the query parser is a CONVENIENCE, not the only way to
build query objects.  If the query parser language is too restrictive,
then build the query objects programmatically.  Its not that hard.

There were reasons why the query language was designed this way.  If
you think that's an error, first you need to lobby for your position
to change the design, THEN we can think about changing the parser.

Parser are tricky.  Small changes can have big, unexpected effects.
Lets make sure we want to do this first (which I think we don't), and
then we can look at the implementation.
