perlfunc/formline: Suggest an alternate capturing method
(When I was starting to program in Perl, I wasted a lot of time trying
to use formline as an alternate version of write, in order to capture
the output. Eventually I created a pipe() and used that. But now we
have scalar ‘filehandles’, it’s much easier.)
