Even so, I would like to understand in what ways the map version of the code above would be less efficient than the more verbose foreach loop

There are only two ways it could be, it uses more memory, or it takes longer, you can Benchmark to find out

But I suspect there isn't much difference in either today, since that statement was published in 1998
