Ah!  That's exactly what I wanted.

I was ignorant of the difference between \&get_body and get_body().

I did previously have a look for the exact meaning of \&, but:
 - my camel index lists many different combinations of punctuation
   characters in the index but  \& isn't one of them
 - googling for: function or \& at site:www.perldoc.com isn't helpful
 - I havn't got my head around perldoc well enough to know where to look.

Thanks
