I can't speak well of my english, but yours seem good to me.

yes.
So you could retrieve the object with a:
probe get bind 'self select h "dolores" ; if you are sure that self is well
defined in the object and "dolores" in the hash

yes
>> h: append append make hash! [] get in ob 'name in ob 'self
== make hash! ["romano" self]
but if you prefer, you could put a direct pointer to the object:
>> h: append append make hash! [] get in ob 'name get in ob 'self
== make hash! ["romano"
make object! [
name: "romano"
]]
