I saw a rather longish program in comp.lang.perl.misc by a fellow Perl trainer and author, and decided that its 15 lines looked far too Perl4-ish and too BASIC-like. So I wrote it as native Perl. It came out shorter than I thought, so I brought it here for the snippets.
chomp(my @lines = <>);
print join(" ", map { s/(.)//s ? $1 : " " } @lines), "\n" while length
+ join "", @lines;
