Looking at http://bugs.squeak.org/view.php?id=5331, it appears that 
problem lie in a primitive plugin.

Obviously, this is a lot harder to maintain than smalltalk code.
I need at least:
- to load VMMaker
- to know a bit of Slang
- to know how to use VMMaker (from within Smalltalk)
- to know how to compile C code produced
Much more than a one hour squeak distraction...

And for maintainers, to compile the plugins on each and every machine, 
update the sites etc... More boring than just uploading an image.

Is it a dream that Exupery could magically do exactly the same job? 
(with a productivity increased x100)

The idea for such a primitive not requiring external call, is that 
Exupery could be specially optimized to generate native binary code 
(instead of C code) based on same slang hints. Possible ?

Just my 0.02€...
