Absolutely - something, as I've mentioned, I think needs to be done at the

I just /hate/ unnecessary tests, and the test will ONLY be valid once, then
it's just extra overhead. I've implemented a form of runtime code patching,
in the current source - but since it's very much x86-32 specific, it could
be turned off for other architectures, and a simple test with hard-coded
branch predictions built in could be used instead. Bear in mind, this code
is platform specific anyway - it's native!

Well, currently, there is no generator - so that's completely open for
discussion! I love the idea of attributes to assist the generator, and
marshalling hints would definitely be helpful.

Oh without a doubt! It would too much of a duplication of effort to go
around parsing the metadata tables. I wrote a simple PE/CLI parser as an
exercise (to keep me occupied one Friday night!) and parsing those tables is
