I should say, that implementation will be somewhat tricky, as different kinds of streams handle reads beyond end in different ways. Say, reading from a pipe whose write end is closed results in an error.

Funny idea.
Here we can also think about MemoryStream: when you have all the data in memory, you don't need user side buffer, and can just return direct slice to data as const(ubyte)[].
