That is a good point. It is a bit tricky, though, since the skip method
does not guarantee efficient skipping. It also reserves the right to skip less
(and return the number of bytes skipped, iirc).
> Allowing users to decorate input streams

> Priority: Minor

> Users may have to do unforeseeable operations on file input streams before
> they can be used by the actual input format logic, e.g., exotic compression
> formats or preambles such as byte order marks. Therefore, it would be useful
> to provide the user with a hook to decorate input streams in order to handle
> such issues.
