byChunk odd behavior?

[Hanh via Digitalmars-d-learn]

Thanks for your help everyone.

I agree that the issue is due to the misusage of an InputRange 
but what is the semantics of 'take' when applied to an 
InputRange? It seems that calling it invalidates the range; in 
which case what is the recommended way to get a few bytes and 
keep on advancing.

For instance, to read a ushort, I use
range.read!(ushort)()
Unfortunately, it reads a single value.

For now, I use a loop

foreach (i; 0..N) {
   buffer[i] = range.front;
   range.popFront();
   }

Is there a more idiomatic way to do the same thing?

In Scala, 'take' consumes bytes from the iterator. So the same 
code would be
buffer = range.take(N).toArray
