Isn't the whole thing overkill?
We already can handle the simple cases:
  cat <<EOD  will use the document as is
  cat <<-EOD will strip leading tabs

If you want anything fancier, you can always used sed:
  sed -e 's!^  !!' <<EOD
or even zsh itself:
  while read -r line; do print -r ${line#  }; done <<EOD
