er... what i mean by this is. i have a small ruby/c extension.
code using it looked a bit like this for example:

   $se.OpCodeVoid(OpCodeFactory.NewLdloc_1)
   $se.OpCodeVoid(OpCodeFactory.NewLdc_I4_1())
   $se.OpCodeVoid(OpCodeFactory.NewAdd())

could be neatened up majorly. but for a few days of hacking
it ain't too bad at all. it can be downloaded from here:

   http://www.lypanov.net/websitedata/monoruby-2003-10-17.tar.bz2

the basic idea:
   could write a ruby -> clr compiler in ruby
   which could later on be bootstrapped if the 
   system.reflection.emit wrapper itself was 
   bound from within.

the method:
   very trivial mono binding based on paolo mauros
   mono-perl. this provides access only to static
   methods. no instances. so rather than hack lots
   in c. i write a c# extension which makes s.r.e
   to static interfaces only. this could of course
   be majorly improved by integrated better with
   mono but i just wanted a proof of concept clr
   byte code generation + execution library.
