[self-interest] Blocks: Summary

[Dru Nelson]

Jecel,

Thanks for you very informative description.

My implementation is using a bytecode interpreter and will have
to implement a test on each push. I might make room for another
type in the references, a block type. That way I could minimize
the hit of the test to a simple AND rather than a proto lookup.

The Self 4.0 compiler is much more advanced than what I will have.

Thanks again,
