Hello,
assignInNamespace refuses to assign an object to a name that is not already
used in the namespace.
That's intentional, and as documented:
‘assignInNamespace’ and ‘fixInNamespace’ are invoked for their
side effect of changing the object in the name space.
^^^^^^^^
I very much doubt we want to allow adding objects.
Even clearer, the Note says
They can only be used to change the values of objects in the name
space, not to create new objects.
Something like this would make it possible:
