Yes it is.  Thanks you very much!  And his blog post describing the
is very good:

http://nic.ferrier.me.uk/blog/2013_06/adding-namespaces-to-elisp

Can't tell, but  it seems the thing fizzled partially because some people
wanted other systems.  I would also prefer CL packages but if a lower
effort thing can solve _some_ problems, and be backward compatible
and not slow down compilation, maybe we should give it a shot.

Anyway, are there any contemporary objections to Nic's plan, in
particular I am interested in knowing if there any any major objections
to Nic's reader logic:

- given a string X
- lookup X in the local obarray
- if it exists return the symbol
- else
-  lookup X in the global obarray
-  if it exists return the symbol
-  else
-    add the symbol to the local obarray
