Counting the size of an array reference

[Tomasi, Chuck]

For a normal array (@MyArray), one can use $#MyArray to get the position of
the last element.

So, if I'm given $MyArrayRef, how does one do the same operation to find out
how many things are in MyArrayRef?

Ex:

sub MySub
{
        my      ($aref)=@_;

        return(______);
}

my @MyArray = (0, 3, 6, 9, 154);

my $LastElement=&MySub(\@MyArray);

print "The last element is: $LastElement\n";



What goes in ___________?
