Comments:
|
As noted in
using types (although this is a function, not a type), you should
not overly rely on the result of this or other similar functions, although you can always trust it when it says
definitely not.

|
Example:
|
integer tid = new_dict()
if not is_dict(tid) then ?9/0 end if

In truth, I would prefer "global type dictionary", but "forward type" has not yet been implemented/tested, and
the equivalent would be needed in psym.e to replace the existing initialAutoEntry("is_dict",S_Func,..) entry.
