def visit_comment(_node)
  # Sass allows you to write Sass Script in non-silent comments (/* ... */).
  # Unfortunately, it doesn't report correct source ranges for these script
  # nodes.
  # It's unlikely that a developer wanted to lint the script they wrote in a
  # comment, so just ignore this case entirely and stop traversing the
  # children of comment nodes.

def visit_script_stringinterpolation(node)
  # We can't statically determine what the resultant string looks like when
  # string interpolation is used, e.g. "one #{$var} three" could be a very
  # different string depending on $var = `'" + "'` or $var = `two`.
  #
  # Thus we manually skip the substrings in the string interpolation and
  # visit the expressions in the interpolation itself.
