Converting from std.file.read's void[]

[Jonathan M Davis]

Okay, it seems that the way to read in a binary file is to use std.file.read() 
which reads in the file as a void[]. This immediately raises the question as to 
how to convert the void[] into something useful. It seems to me that casting 
void[]  to a ubyte[] is then the appropriate thing to do because then you can 
properly index it and grab the appropriate bytes that need to be converting into 
useful values. However, that still raises the question of how to get anything 
useful out of the bytes. UTF-8 strings are easy because they're the same size as 
ubytes. Casting to char[] for the portion of the data that you want as a string 
seems to work just fine. But what about other types? Is it the correct thing to 
cast to T[] where T is whatever type the data represents and then index into it 
to get the values that you want of that type and then cast the next section of 
the data to U[] where U is the type for the next section of the data, etc.? Or 
is there a better way to handle this?
