I came to the same conclusion. (So I'm not losing my mind.)

I have decided NOT to go this route. Instead, I'm going to use arrays. 
When an event is constructed, it builds an array of all data pertinent to 
itself. Then we ask for this data:

proc handle_foo_event {foo_event} {
  array set fooData [$foo_event get]

  puts "varA = $fooData(varA)"
  puts "varB = $fooData(varB)"
}

Ugh. I thought breakpoints would be easy. Guess again. Can anyone guess 
the difference between clear_command and delete_command (other than 
argument)? I'll give you a hint: using clear_command is EVIL.
