You could either put the code in the headers for the relevant classes, or the base mechanism in WTF and specific overloads in a catchall header for WebCore. You don't have to put the basic mechanism in WebCore just to have overloads for WebCore types.

And I don't see the circular dependency.  And if you wanted to have a wtfPrint() for IntRect, then couldn't you put the appropriate overload(s) in IntRect's header file?
