+# It may be argued that
+#   x=$(cat <<EOF
+#   foo
+#   EOF)
+# is a valid complete command that sets x to foo, because
+#   cat <<EOF
+#   foo
+#   EOF
+# is a valid script even without the final newline.
+# However, if the here-document is not within a new-style command substitution
+# or there are other constructs nested inside the command substitution that
+# need terminators, the delimiter at the start of a line followed by a close
+# parenthesis is clearly a literal part of the here-document.
+
+# This file contains tests that also work with simplistic $(...) parsers.
