One more thing I've just noticed:

The perldelta fragment mentions for(scalar($#foo)) { ... }. But what does this even mean? Why would anybody do this? $#foo is already a scalar (the index of the last element of @foo), why would anybody call scalar on it, and why would anybody use it in a foreach?

If you want to enlarge or shrink the array via $#foo, you can do it simply by $#foo = 43;. This foreach nonsense is just obfuscation and I don't see why was it "corrected".
