Are you sure MyClass::DoSomething is legal C++ for getting a pointer
to a member function?

A google for "C++ member function pointer" lead me to
http://linuxquality.sunsite.dk/articles/memberpointers/ which states
the following:
"For regular function pointers, it is optional to use the address-of
operator & when taking the address of a function, but it is required
for taking the address of member functions. g++ will compile source
that leaves it out, but emits a warning."
