    When you declare %fields inside the scope of the foreach $item (@pairs) loop with my, its contents are private to that loop. Then you try to access %fields after the loop, but it doesn't contain anything since you're outside the closing bracket (scope) of the for loop.

    -w and use strict tell of such errors.

    With your my declaration in the foreach loop you declared the hash locally.
    So the values you put into it weren't known outside.

    With using strict something like this can't happen because perl will give you an error.

    Have a look here for something more on my.
