The biggest problem with this particular example is not the operator 
overloading, but the bare word "Price", which is currently a constant 
lookup, not a class reference, as in:

const Price = 50;
var_dump(Price < 100);


However, with any version of operator overloading that didn't limit the 
return values of the overloaded operator, you could do something like:

$query->where(Product::$price < 100)

Where the static property Product::$price is an object which overloads 
the "<" operator to return some kind of Condition object which can be 
used by the query builder.
