Hello again Sean,

looking at your code…now I think that Alex answer was the  right one :)
in fact one should be able to open a world in a world.
one should be able to script a space,
thus, one should be able to write a test with a local BlocSpace, adding elements into it and so on
but your code does not make sense regarding how Bloc is designed
you can have one and only one **active** BlocSpace at a time.

imagine that a BlocSpace is a Pharo image.
Making your code working would mean that we would be
able to run a Pharo image within a Pharo image.

this does not make sense for me

this can make sense

this canot work also because only the current space can draw.

ok, at least it means that we have to write good documentation about the bloc design.
