Would there be any way to achieve normal indentation with this
approach?  How about

  s = <<|
    | Now is the time
    |  For all good men
    |     to code Ruby

But anyway, "FOO" isn't dead yet.  You may not use the "plus bar"
example above, but what about this?  (Again, you may not use it, but
I'm sure it's used somewhere.)

  foo "one", "two"              # simple text

  foo <<-END1, <<-END2          # multi-line text
    Abraham
  END1
    Lincoln
  END2

Hey, I don't use it either, but I can't see this being dropped from
the language all of a sudden.
