in thread the basic datatypes, three

assigning a list to a scalar variable returns the result as a total number of elements in a list

No. That's not right. Evaluating a list in a scalar context (by, for example, assigning it to a scalar) returns the last item in the list. Evaluating an array in scalar context returns the number of items in the array.

There is an important difference between a list and an array.

# Assign a list to a scalar my $scalar = ('A', 'B', 'C'); print "$scalar\n"; # $scalar is C # Assign an array to a scalar my @array = ('A', 'B', 'C'); $scalar = @array; print "$scalar\n"; # $scalar is 3
Update: Stupid typo fixed.
