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

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