Yes, I would like such a system too.
But right now, Huemul is very far away from that.
Huemul's core is still in C. To translate it to ST, I would need your
compiler.
That is why I asked you about it. Klaus suggested that it would be
interesting to use it, just the way you want.
I am getting close to a Huemul release that doesn't need Squeak. When that
is done. I will finally release source code, for anyone to play with it.

PS: May be the example about changing SmallInts behavior would be a bit
difficult to implement. Not the part of getting 0 or 1 tagged arithmetic,
that part would be easy to implement for both behaviors. The problem is
the way you access the other objects. It is much more difficult to access
an oop with a 1 tagged int system, than a 0 tagged one. Believe me, the
hardest part of implementing 0 tagged wasn't the arithmetic part, at
least, that was my experience with Huemul. But apart from that, I got the
idea behind the example, and I agree with you.
Yes , its somewhat complex and requires a special handling in many
places, but still, this can be implemented at abstract level , such
that any dependant code don't require any additional changes.
Another example: on 64 bit systems we can use 2 bits for tag, and be
able to make smallints, floats,chars immediate values.
If someone wants to keep boxed floats, so just let him do this , all
he's need is to supply a class name, which holds all low-level
primitives written by him for that purpose.
