Peder Holt adapted this method to VC7.0, where the nested class
is a template class that is specialized in the derived class.
The loopholes have been fixed in VC8.0 though, so on this compiler
this method doesn't work.
In VC8.0, it seemed that all the bug-featire had been fixed, but
Steven Watanabe managed to implement a more rigorous version of the VC7.0 fix that
enables 'typeof' to be supported 'natively' here as well.
For this and many other compilers neither native `typeof` support
For many other compilers neither native `typeof` support
nor the trick described above is an option. For such compilers
the emulation method is the only way of implementing `typeof`.
