Generally the D answer here is to put them in separate files. The
module (file) is the main D encapsulation unit rather than the
class/struct.
It isn't the same as C++ but I find it works pretty well - you
often do one file per class anyway, and files are a natural unit
for encapsulating too.
I'm sure "friend" explodes the basics of OOP encapsulation
mechanics.

If you have helper structures it can be useful to get at the
private parts anyway, for example an iteration range.
