Summary: [namespace which -var] fails for ary(i)

Initial Comment:
[namespace which -variable ary(i)] returns a null 
string even when ary(i) exists! This is a major pain
when trying to get fully scoped variable names to give 
to widgets. Here is a script snippet that shows the 
eror:

(1) Sorry, this bug somehow flew under my horizon :( 

(2) It's not so clear to me what the correct fix would be:
what should happen if the array itself exists, but the array
element does not? In your script, what is the expected
result of adding a line
   puts "4 - [namespace which -variable ary(k)]"
According to the man page, the return should be "" - is this
what you're expecting?

(3) Depending on the answer to (2), a workaround involving
[info exists] may be the solution for now.

Got submitted to quick...
namespace eval a {
  variable ary
  set ary(i) v
  puts "1 - [namespace which -variable ary]"
  set x ary
  set y ary(i)
  puts "2 - [namespace which -variable $x]"
  puts "3 - [namespace which -variable $y]"
 }
