in thread Get the length of a list.

Nope, evaluating a list in scalar context returns the length of the list.

You seem to confuse lists and arrays.

    You are correct choroba.
    Thanks for pointing out my error :)

    perldata - Context highlights the difference between scalar(array) and scalar(list):
    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.)
