Hi,
when redefining new you don't have to use super:
BlElement class>>new
    ^ self basicNew 
        basicSpace: BlUniverse default runningSpace;
        initialize;
        yourself
IMO that's a better practice that redefining basicNew.
I just sent the same example ;)

Usually basicNew is only redefined when you cannot instantiate the objects using the normal API because it is not supported by the runtime (SmallInteger, Context, etc.)

this is badâ¦ redefining basicNew should not be done, never, never, never.
why ?
...
thatâs why we have new and basicNew :)
the space may be needed during #initialize.
this is why the initialization of the space is done in
basicNew.
But ok, we will fix that.
Thanks
