<P><FONT SIZE=2>Hi all,</FONT>
</P>
<P><FONT SIZE=2>If I have a function:</FONT>
</P>
<P><FONT SIZE=2>it f [a0, a1, a2, ...] = [a0, f a1, f (f a2), ....]</FONT>
</P>
<P><FONT SIZE=2>Is there any way of expressing</FONT>
</P>
<P><FONT SIZE=2>it f</FONT>
</P>
<P><FONT SIZE=2>as an instance of foldr?</FONT>
</P>
<P><FONT SIZE=2>Many thanks,</FONT>
