There is a built-in function to sort a list, yes. But the mechanism by
which to sort the list is, in this case, up to you to provide. This works:
my @sorted = sort {
$a->[0] <=> $b->[0]
} @employees;
However, is this scalable if, for example list is more than 5000 ?
Sure, it's scalable... I believe perl uses a mergesort nowadays, which is
better on larger lists anyway. Regardless, given the data you showed us,
this is the simplest and shortest (and most likely fastest) way to sort it
based on a given index.
