# ExtraAttributes: An object that lets you sneak as many return values as you want
# through a single scalar-looking return value.
# Any return values set are immutable.
# Example usage:

module StringUtils
  # Unindents a multiline string,
  # even if the first line is not the one with the least whitespace.
  # Best used with heredocs like this: <<-EOS.unindent ...
  # Note that if there are lines that are just newlines that
  # those will not break the next minimum indent length due to (?!\n) in the regex.
  # This is to get around editors which auto strip trailing whitespace on lines.
  # Otherwise any stripped whitespace on a blank line would kill the unindenting.
