Hm, after going over the archives, it seems that there was originally an 
initiative to have compile-time converter-generators, but this idea kind 
of fell away in favor of on-demand argument conversion.

The compile-time approach or something similar is necessary to generate 
the native functions for a Java class; the arguments of the native 
function have to be declared -- that is, there isn't a "blob" of Java 
arguments that can be parsed at runtime.  There are a couple of 
alternatives that I've thought about, but they aren't very attractive 
(at least to me).

When we can get around to discussing it, I'd like to discuss the idea of 
maybe bringing the compile-time idea back.  In the meantime, I'll see 
what I can do to sketch out something relating to the compile-time 
approach on my own using fusion/mpl.

Thanks again for your attention.
