Yes, this is the tex that gets output:

\code{mlazy( <{}<objname1>{}>, <<objname2>>,
<<etc>>)}

This seems to happen in Rdconv.pm, around here:

     ## avoid conversion to guillemots
     $c =~ s/<</<\{\}</;
     $c =~ s/>>/>\{\}>/;


But I don't know enough Perl syntax to tell it to replace all << by
<{}<, instead of just the first.  (I would have guessed appending a g
would work, but didn't in a quick test, i.e. $c =~
s/<</<\{\}</g; didn't
work.)
