Only if you can convince Rob to add a function to return the
(momentary) address of a sequence. As well as some kind of a
lock function to prevent garbage collection and sequence copying
from taking place while you work with the structure. Otherwise, it'll
be gone by the time you're ready to write something there.

Odds of Rob doing this are less than .01%, I think.

Yes, proper handling of namespacing is a far better solution to this
problem than "if defined" could ever be. See just about any C program
for proof of the awkwardness of that approach.

Besides, I see no way that "if defined" could help in the situation you
propose:

if defined x then -- oh,oh, x was already used in Win32lib
  constant myx = 3
elsif defined myx then -- oops, myx declared in Jiri's fonts
  constant anotherx = 3
elsif defined anotherx then -- oops, declared in Freds Functions
  constant yetanotherx = 3
....
After all this, how does your program know to refer to yetanotherx
in place of the original x?
Do you have to change all the following code?
