   3 # It may be argued that
   4 #   x=$(cat <<EOF
   5 #   foo
   6 #   EOF)
   7 # is a valid complete command that sets x to foo, because
   8 #   cat <<EOF
   9 #   foo
  10 #   EOF
  11 # is a valid script even without the final newline.
  12 # However, if the here-document is not within a new-style command substitution
  13 # or there are other constructs nested inside the command substitution that
  14 # need terminators, the delimiter at the start of a line followed by a close
  15 # parenthesis is clearly a literal part of the here-document.

  17 # This file contains tests that may not work with simplistic $(...) parsers.
  18 # The open parentheses in comments help mksh, but not zsh.
