Hi,

I wrote a program as this:

  set my_result ""

First mistake (although minor):

Try this instead:

    set my_result [list]



<snip>

How is that even a minor mistake? The result of [list] is "". If the
idea is to indicate that my_result is a list then I think this is the
wrong way to do it. As EIAS the intention is much clearer (throughout
the code) by an appropriate variable name (such as waiting_list).
