Here Documents in commands

hello, world\n

I've been thinking long and deep and even made a few attempts at using
shell "here documents" in the commands for a rule. My conclusion is that
it is impossible, at least with a POSIX shell. Make's command execution
with sh is inherently line oriented, while here documents are multi-line
by definition. Continuing lines in the Makefile with backslash newline
can't work because the shell only sees the resulting single line.

In the remote event that I have overlooked something, does anyone
know a way how to get something like

        cat << EOF

in a rule?

PS: Yes, I can get the same effect with a fews echos. Consider it a
    proof-of-concept question.
