I've finished the port of boost.uuid to D and I'd hope to get some initial
feedback.
Quoting the module documentation:
This is a port of boost.uuid from the boost project with some minor
additions and API changes for a more D-like API.
A UUID, or Universally unique identifier, is intended to un

Very nice. I will need UUIDs in one of my D projects :)
This module also depends on Piotr Szturmaj's crypto library to generate
level 3&5 UUIDS. The code for this is written, but wouldn't

Weakly pure, yes - but for what?. Btw. I just gave a try at compile time
evaluation of these hashes. I got rid of memcpy but then endianness

In general, if a function _can_ be pure, it _should_ be pure. If it can be and
it isn't, it artificiall

We really need to find a way for the C memory functions to be considered pure

Where does your code use memcpy? I see one mention in the

none in the code.
See putArray() in base.d
