// wxRemoveRef<> is similar to C++11 std::remove_reference<> but works with all
// compilers (but, to compensate for this, doesn't work with rvalue references).

// Except that it doesn't work with VC++ 6 as there doesn't seem to be any way
// to partially specialize a template for references with it.
