I'm having a hard time following why. Can you provide an example of a
Ruby snippet that couldn't be done with scoping defined by
indentation?

This seems like a problem with Python, not a problem with indentation.

Again, I would really like to see an example of the sort of thing
you'd want to do here that simply requires "end" to work.

Well, every expression in a Ruby-like grammar must be terminated by a
token. What that token must be depends on the grammar. Why not
something like this? (and please forgive the highly unorthodox
pseudocode syntax)

parse_line_indent:
  if indentation = previous_line_indentation: do_nothing
  if indentation > previous_line_indentation:
push_indentation_to_indent_stack_and_enter_new_scope
  if indentation < previous_line_indentation:
    while indentation > top_of_indent_stack:
      insert_backtab_token   # here's your statement terminator
      pop_top_of_indent_stack
    if indentation != top_of_indent_stack: raise IndentationError

In other words, the parser treats an indentation level less than the
indentation level of the previous line as a statement-terminating
token.

This sorta makes sense but I'd really like to see a concrete example
of what you're talking about. It doesn't seem like this would be an
insurmountable difficulty but it's hard to say without the example.

Being completely unfamiliar with Haskell (functional programming's
never been my strong suit) I can't really comment.

I'll be glad to take the benefit of your practical experience, but at
the risk of seriously violating DRY, some sort of demonstration of
something that you can do with "end" but couldn't do with indentation
would be nice.
