> Sorry for the title, hard to explain in a few words:

This has nothing to do with AliasThis. All forward ranges behave this way with
foreach (i.e. foreach operates on a `save`'d copy).

When `save` is not necessary (such as in algorithms that have already called
`save`), a for-loop should be used, as seen in many places in Phobos.
