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,

that's due to absense of modules in C/C++. and namespaces aren't of big
help here too. and, of c

I had seen some stuff on alias thing, but I hadn't bothered to
try to understand it until now. If I'm understanding the first

alias this let's you refer to x in s by writing either s.x (as

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.
