I never knew that. I was relying on the ID byte.
I now use upper flag bits of the type to distinguish ASGN as
private/public, and to-name/to-noun.
I needed to distinguish named private assignments in explicit
definitions, because I preallocate symbols for them in a symbol table
that I also preallocate, and point each reference to them to the
preallocated symbol to avoid the name search during execution.

ASGN is an internal type; in the value part (the ravel) of a scalar with
that type, there is a 0 or 1, indicating whether is local assignment (=.)
or global assignment (=:).

Aaaghh, you caught me. That was one of the first changes I made when I
was learning the J Engine. I knew it would print wrong, but I didn't
know how to make it right, and I hoped no one would ever notice.
I guess I have to go back and fix it, but I understand the system better
now, so maybe I can figure out how to do it properly.

NB. Curious -- why is =. changed to =: for error reports in recent
versions?
