power of explicit self?

[Fire Crow]

I'm looking for an explanation of how explicit self is implimented and
what features are only possible because of, or are greatly improved,
because of it. I've always liked explicit self and am looking for the
computer science behind it, so that I can explain the benefits that I
see.

I'm also interested in the files/lines of the python source that shows
how explicit self is implemented if anyone can point out where that
takes place.

all help welcome
