[plt-scheme] Re: Getting started embedding mzscheme in Windows/VS2008

I am currently trying out a combination of mzscheme extension API and C
++ template metaprogramming, as described here:
https://trac.v2.nl/wiki/vge/MagickWrappers

Would be nice if there was an easier way, but blame that on C++.. ;)

Any pointers (pun intended?) appreciated, though.
