An array in scalar context will return the number of elements in that
array so the expression ($i %= @array) is the same as ($i %= 10) if
@array has ten elements or ($i %= 200) if @array has two hundred
elements.

Normally screen output is buffered and won't appear on the screen until
a newline is printed. Turning on autoflush lets output appear on the
screen without a newline.
