Blessings upon ye, Monks of Perl.

I recently embarrassed myself by asking TT & templates from data?. And here is another, hopefully less stupid question:

Is there a way to make Template::Toolkit process the contents of a variable inside of a template?

E.G.


my $vars = {
    header => 'hello, [% name %]',
    footer => 'goodbye, [% name %]',
    name => 'Dave',
}

my $template = <<"END";
[% header %]
I'm afraid I can't do that
[% footer %]
END

my $TT = Template->new();
my $output;
$TT->process(\$template,$vars,\$output) || die $TT->error();

[download]

If "header" and "footer" were external files, I could INCLUDE them, but they are scalars.

I was able to make it work by running process twice:

$TT->process(\$template,$vars,\$output) || die $TT->error();
$TT->process(\$output,$vars,\$output) || die $TT->error();

But I'd rather do something less kludgey and more scalable.

Thanks for any ideas!
