"long" in D is a 64-bit integer, therefore you should use "%ld" to print 
it using printf. Generally, try to cut back on the use of printf since 
it doesn't check the arguments, causing many similar problems. You 
should use writefln/writef (from std.stdio) instead. In writefln you can 
  simply use "%s" for all types.
