Description: Here Documents and Command Substitution

The following syntax do not work (parse error).

echo $(cat <<-EOF
        this is a )
        EOF
)

This syntax work. But it's not following the Here document rule:
       This type of redirection instructs the shell to read input
       from the current source until a line containing only  word
       (with  no trailing blanks) is seen.

echo $(cat <<-EOF
        this is a space.
        EOF)
