I, too, had not clue about this until now.

Does those "alternate streams" belong to filesystem library at all?
For one thing, the ':' symbols is not allowed anywhere except for root name.
For another thing, on all systems but NTFS, "bar.baz.blip:blat" would be
considered as having "blip:blat" extension, and making the function behave
differently on NTFS is confusing. Lastly, the 'extension' function is
supposed to do only syntax transformation, but to tell if you're on Fat32
or NFTS you'd need to ask operating system...
