It *might* be possible to improve the display. ---- `a ,= b` is just shorthand for `a = a , b`. This same pattern is used for any `a op= b`. So `a += b` is the same as `a = a + b`. So `@r ,= 'd'` is the same as `@r = @r, 'd'`. Which makes @r a self-referential infinitely recursive data structure. How does one display it? I can imagine an argument that it would be better if the *gist* (as against the `dd`) switched from: @array_123456789 to @r or @array-that-contains-itself or @array-that-contains-itself_1 But I'm not sure if any of those suggestions are *improvements*, nor whether they are viable / sensible. ---- > Do the "docs" page(s) make more sense changing the phrase > "class-dependent" behavior to "hash-dependent" behavior? The "class dependent" behavior is really a red herring. See my other other reply to Joe for a detailed discussion.
