Function where() might fail when used with two params

[duxet]

Using where($field, $value) fails when $value is same as one from the available operators, eg:

Model::where('field', 'mod')->get();

InvalidArgumentException: Value must be provided.

eh, variadic functions and argument unpacking would be very useful in fixing that :p
