Absolutely. You can do list-oriented programming in Perl as well. The problem that arises is that while doing list-oriented programming you lose the ability to do certain text manipulations without breaking the list-oriented style. For instance, you run afoul of problems with regular expressions over a string if you represent the string as an array. Similarly, you must convert to a list when you read strings in from external sources.

There are many things that Perl does better for text processing than UCBLogo, but I think UCBLogo wins on this one score.

print substr("Just another Perl hacker", 0, -2);
