I agree that many constructs (s///, tr//, ``) will be familiar to someone with Unix background, but I'm not sure if they would qualify as a novice (many CS first years are unfamiliar, and in fields like bioinformatics -- where Perl happens to be the most commonly used language -- it's a rarity). But anyway, what about $_ and a host of other special variables? Pulling arguments to functions out of nowhere? Using regexps for simple string operations? Strings not being array? Using a special comparison operator for strings (without complaints when == is used)? length() not working on arrays (again, no warning) and $# returning index of last element rather than length? 'if' not being able to take a single statement? 'Last' instead of 'break', 'next' instead of 'continue', 'continue' doing something else?
