My guess is a combination of not understanding scalar context and
copying code from a book that didn't understand scalar context.  ("To
find the length of an array, use $#ARRAY + 1.")

I once read a Perl book that suggested that being able to evaluate an
array in scalar context was a bug that a future version of Perl would,
hopefully, fix.
