I know that lists and arrays are different, but as yet I haven't found in the documentation what the difference is. Where in the documentation is the difference between lists and arrays explained? I found this in perldata:

If you evaluate an array in scalar context, it returns the length of the array. (Note that this is not true of lists, which return the last value, like the C comma operator, nor of built-in functions, which return whatever they feel like returning.)

There is also a section on slices in perldata, but where does it say that a slice is a list?
