"index" is a better term
You usually don't need to use that syntax, however. Use
@MyArray in a scalar context.
$MyLen = @MyArray;
o
$#{ $MyArray } will give you the position of the last element.

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?

sub MySub
