Hi!

Just a brief note to say that if you haven't noticed, the "master"
branch of Guile now compiles to the new virtual machine, using the new
compiler.  All tests pass.  The old VM is gone!

There are a couple of regressions that I would like to fix soonish:

  * The compiler is somewhat slow.  I haven't tried to optimize it at
    all, so there's lots to do here.  To a degree it is to be expected,
    as the compiler does more work -- but I hope to get it faster than
    the 2.0 compiler.

  * We don't have local variable information.  In the debugger, ,locals
    doesn't print anything.  Here we need to build this information at
    compile-time, write it into ELF somehow (perhaps using DWARF), and
    read it out as needed at runtime.  I'll take a look at this too.

  * The manual is out of date, as regards the compiler and VM.

Besides these regressions, there are a many optimizations to make --
many more than before -- now that we have a better intermediate language
in which to express them.

Let the list know if you find any problems that aren't covered by the
test suite.

I hope we can get out a 2.1.0 release -- which would be a prerelease for
2.2 -- around mid-December or so.  We can aim for 2.2.0 for next May or
so, but that's a totally fictional date I just made up :)

Cheers,

Andy
