What's the correct way to copy a `File` into another one in D?
If `LockingTextReader` wasn't undocumented, I'd have gone for that
approach:
import std.algorithm.mutation : copy;
import std.stdio : File, LockingTextReader;
void main()
{
auto a = File("a.txt", "r");
auto b = File("b.txt", "w");
a.LockingTextReader.copy(b.lockingTextWriter);
}
Side-note:
Although the example code suggest otherwise, I'm not talking about
copying actual files on disk. In such a case I'd just use
`std.file.copy` ;)
So, just imagine `a` were `stdout` of process pipe.
Kind regards,

I would probably start by reading it byChunk and writing it out as a
rawWrite or something along those lines. That way its using a nice
buffer (to limit memory usage).
