It seems as though the following calls do what you'd expect (close the stream and not allow any further input - anything waiting for input on the stream returns error), but is it guaranteed to be correct across all compilers/platforms?

If I've got a List with the following entries:
Apple Banana Grape Cherry Orange Kiwi
Is the result of
fruit.FindAll(f => f.Length == 6)
guaranteed to always be
Banana Cherry Orange
or could the order be different?

The documentation.
It's not guaranteed in the sense that it doesn't say it in the documentation, however if you look, although it doesn't explicitly say that it is guaranteed to be in the same order.

Given something like
foreach (keys %myHash) { ... do stuff ... } foreach (keys %myHash) { ... do more stuff ... }
Is Perl guaranteed to iterate over the keys in a consistent order if the hash is not altered?

Working around the edges.
Then, you're guaranteed to access keys in same order.
Order is subject to change in future versions of perl, but it is guaranteed to be the same order the saved result.

Yes, the intention of the manual is indeed to guarantee that sorted is stable and indeed that it uses exactly the same algorithm as the sort method.
