From perldata:

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.)

An empty list doesn't have any values, so trying to get the last value gives you undef.

We're not surrounded, we're in a target-rich environment!
