// This file makes use of both the ObjC DOM API and the C++ DOM API, so we need to be careful about what
// headers are included and what namespaces we use to avoid naming conflicts.

// FIXME: This has to be in the KJS namespace to avoid an Objective-C++ ambiguity with C++ and
// Objective-C classes of the same name (even when not in the same namespace). That's also the
// reason for the use of objc_getClass in the WRAP_OLD macro below.

// Some day if the compiler is fixed, or if all the JS wrappers are named with a "JS" prefix,
// we could move the function into the WebCore namespace where it belongs.
