Yes, that's the other option but it is a bit more work. The "luxury" version I
was thinking of would have something like
FooBar = dllcaller('FooBar', formatstring)
where formatstring would somehow describe the arguments and return values.
dllcaller would then return a callable object with the correct calling
sequence, and it would perform argument checking.
