Explicitly, it usually isn't; but I believe that abstract algebra and linear algebra cannot be understood without implicitly seeing variables as objects.
For example, if you are going to think about the vector space of polynomials, you can't be thinking of "x" solely as a placeholder for a number  you're sitting there waiting to find out what "x" *really* is, when, in that sense, it isn't.
