I don't think you've read h5py source in enough detail :)
You're right - I haven't done more than browsed it.
It's based HEAVILY on duck typing.
There is a question here about what to do in D. On the one hand,
the flexibility of being able to open a foreign HDF5 file where
you don't know
In the hierarchy example above (c++ hdf hierarchy link), by
using UFCS to implement the shared methods (which are achieved
by multiple inheritance in the c++ counterpart) did you mean
something like this?
// id.d
struct ID { int id; ... }
// location.d
struct Location { ID _id; alias _id
struct File { Location _location; alias _location this; ... }
// group.d
public import commonfg;
struct File { Location _location; alias _location this; ... }
// commonfg.d { ... }
enum isContainer(T) = is(T: File) || is(T : Group);
auto method1(T)(T obj, args) if (isContainer!T) { ... }

I see, thanks! :) I've started liking structs more and more
recently as well and been pondering on how to convert a
class-based code that looks like this (only the base class
has any data):
it's hard to tell by brief description. but having multiple
inheritance

that's due to absense of modules in C/C++. and namespaces aren't

I'm new to D. I have some modest knowledge of C++, but am more
familiar with scripting languages (Matlab, Python, R). D seems so
much easier than C++ in a lot of ways (and I just learned about
rdmd today, which is pretty cool). I am concerned about
performance of D vs. C++, so I wanted to

Thanks for the reply, I wasn't familiar with scoped. I was aware
that structs are on the stack and classes are on the heap in D,
but I didn't know it was possible to put a class on the stack.
Might be interesting to see how this is implemented.
