What is the difference between $array[1] and @arra

(From the Perl FAQ) What is the difference between $array[1] and @array[1]? The former is a scalar value, the latter an array slice, which makes it a list with one (scalar) value. You should use $ when you want a scalar value (most of the time) and @ when you want a list with one scalar value in it (very, very rarely; nearly never, in fact). Sometimes it doesn't make a difference, but sometimes it does. For example, compare: $good[0] = `some program that outputs several lines`; with @bad[0] = `same program that outputs several lines`; The -w flag will warn you about these matters.
