Named scopes are great.  You can compose huge queries by gluing
parts together.

u = User
u = u.employee if params[:employee]
u = u.unvested if params[:unvested]
... etc.
u.length   -- returns the number of users matching the query.

Works great if you specify either parameter.  You end up with one of:

    User.employee.length
    User.unvested.length
    User.unvested.employee.length

However, if both scope1 and scope2 are false, you end up with:

    User.length

Which fails.

Is this a design hole in named scopes?  Is there a way to
make this work?  It should of course return a count of every
user if none of the scopes are applied.
