my hope is that it will lead to a different and more high-level
development approach for the Squeak VM. While Slang does a good job
for the VM as it is, it is certainly not using high-level abstractions
(and never had the intention to), which would be much more convenient.

Of course, high-level abstractions may prevent dealing with low-level
details, which are all over the place in VM implementations. This is
where the tool chain comes into play: the gory details are realised by
means of applying smart tools to the high-level source code.

I think the PyPy approach is extremely promising.
