Summary: upvar to array element and trace non-functional?

Initial Comment:
This behaviour is present since (at least) Tcl8.3. Is
it a bug? I did not find it documented ...

% set a(1) 2
2
% trace add variable a read {puts READ;#}
% set a(1)
READ
2
% upvar 0 a(1) x
% set x
2
% set y 1
1
% trace add variable y read {puts READ;#}
% set y
READ
1
% upvar 0 y x
% set x
READ
1
% trace add variable a(1) read {puts READ2;#}
% upvar 0 a(1) x
% set x
READ2
2

Doh - duplicate. Thanks Don.

Interesting that I did not find the docs ... whereas I
pointed to them myself in 572889.
