[phobos] returning void[] from std.file.read()

[Andrei Alexandrescu]

This has come up in http://d.puremagic.com/issues/show_bug.cgi?id=1482. 
Should std.file.read() return void[] or ubyte[]? There's one matter with 
assuming that void[] may contain pointers (which is not the case for 
something read from a file), so possibly ubyte[] is a more accurate type 
for describng raw bytes.

What are the pros and cons of returning void[] vs. ubyte[]?
