…inter widget names
The "!" prefix has a special meaning in the tag expressions of the
canvas and text widgets ("!", "&&", "||", "^" and parentheses), so an
automatically generated widget name could not be used as a tag. "+" has
no special meaning there, nor in option database patterns or Tcl lists,
and a user is very unlikely to start an explicit name with it.
