Arrays - Context

Notice that I put the previous inside parens.  I have done this to represent "list context."  This means that Perl acually returns a list with one item and four undefined items in it rather than the one item itself.  This can be important:


    @bar = @bar[0,2,4..6]
    # @bar is now as above.  Again we killed the "cat"
    $foo = @bar[0,2,4..6] # $foo is undef
    $foo = @bar; # $foo is 5
