Yikes, fair enough.

I actually really wish lit had some support for the here-document pattern:

  cat <<EOF
  $foo
  EOF

We could replace many uses of echo in our test suite with this, but it's not clear how it interacts when prefixed with `# RUN: `, and we'd have to implement it in the builtin lit shell for Windows. I proposed a tool to extract such tagged regions from a file before, but some senior contributors opposed it.
