Oh, well :) I would certainly be interested to see what you have, even if not finished yet. My focus was sadly getting something working soon in a sprint, rather than building something excellent later, and I would think your work will be cleaner. In any case, I would very much be interested in exchanging ideas or working together - on HDF5, on multi-dim or on other projects relating to finance/quant/scientific computing and the like. So maybe you could send me a link when you are ready - either post here or my email address is my first name at my first name.com Thanks.

Github here: https://github.com/Laeeth/d_hdf5 I wonder how much work it would be to port or implement Pandas type functionality in a D library. @Laeeth As a matter of fact, I've been working on HDF5 bindings for D as well -- I'm done with the binding/wrapping part so far (with automatic throwing of D exceptions whenever errors occur in the C library, and other niceties) and am hacking at the higher level OOP API -- can publish it soon if anyone's interested :) Maybe we can join efforts and make it work (that and standardizing a multi-dimensional array library in D).
