- A little comment here
-
- My previous attempts to use operator()(...) and operator FuncPtrType () with MSVC
- failed, where FuncPtrType is a function pointer typedef. That technique, enables
- more control over a functor object. ie: can implement delay load among many exciting
- features. That technique, however, works with g++ line of compilers.
-
- This current implementation is design for use with MSVC line of compilers only.
-
- It seems, from the MSVC compiler error message, that "operator FuncPtrType ()" is
- never a candidate function, not to mention viability. I guess this is how they
- design and implemented MSVC6. ".net" version doesnt "evaluate"
- "operator FuncPtrType()" properly as well.
