(feature request) here-document, but from a file

[William Park]

Dear Chet,

It would be nice if I can read a file and process it as though it was
here-document text in the script.  Mainly, I want variable substitution,
without calling lots of 'sed'.

In Python, you would do
    print "..." % ...

So, perhaps, you can use syntax like
    cat <<+ file
    cat <<<< file
