You are right. I hadn't read the documentation carefully enough and hadn't spotted that. Running hexdump -C shows that a seek is indeed necessary.

$ perl -Mstrict -Mwarnings -e '
> open my $fh, q{>}, q{rubbish} or die $!;
> print $fh qq{A longish line of text\n};
> truncate $fh, 0 or die $!;
> print $fh qq{Short\n};
> close $fh  or die $!;'
$ cat rubbish 
Short
$ hexdump -C rubbish

Thank you for the correction.
