In place of all of the special rules for handling indentation, I wonder if they could simply define some extra starting chars (besides $$""" for controlling interpolation) to indicate suppress-leading-newline or suppress-ending-newline etc. Offhand this would seem more explicit than implicit, and be searchable (unlike a pattern). Other than that, ++ for any mechanism to quote to arbitrary depth. I have imagined [abcfoo[ ...anything but ]abcfoo]... ]abcfoo] as another approach.
