 Two things: one, std.file.read returns a void[], which is a bit like D's 
 equivalent of a void*


I don't understand the design of that std.file.read(): why don't return a
ubyte[] by default instead of a void[] (and cast it to everything else if you
don't need ubytes)?

1) It doesn't matter.  You're supposed to cast it anyways based on the type of
data in the file.
