the |_self> ket

Next feature I want to mention is the |_self> ket.
I use it all the time, and hopefully is not too hard to describe.

Recall my standard learn rule:
OP KET => SUPERPOSITION
well, simply enough, if |_self> is mentioned in the SUPERPOSITION (on the right), then substitute in the value KET.

Simple example I suppose:
sa: op |x> => 100 |_self>
sa: dump
----------------------------------------
|context> => |context: sw console>

op |x> => 100.000|x>
----------------------------------------
See? We have 100 |x> on the right of our learn-rule, not 100 |_self>
And that's about it. Nothing complicated about it at all.

More to come!
