D tends to prefer structs with UFCS member functions rather than 
classes, because one rarely needs the reference semantics or 
inheritance. Also, classes are pretty inconvenient because they 
are hard to use without the GC.

`private` is for outside the module. Within the module, private 
is not applied because D wanted to avoid C++'s `friend` functions.
