Hello!
It looks like SciD [1] is obsolete and work on its reincarnation [2]
have not been started yet.
Here is yet another linear algebra library for D:
https://github.com/MaksimZh/linalg/wiki
It was inspired by proposal [2] but has some differences:
1) Support of immutable data and pure functions.
2) No reference counting, no copy-on-write.
- It looks completely incompatible with immutable matrices.
- Unpredictable GC allocations make people sad [3].
So matrices act like built-in D arrays: slice is a view, copying is
forced with `.dup` etc.
3) Support of backends that can be enabled with compiler options (e.g.
-version=linalg_backend_lapack) and add optimization and new features.
The library works even without any backend.
In current (pre-alpha) version this feature is just outlined: enabling
LAPACK adds evaluation of eigenvalues for `Complex!double` matrices and
activates corresponding unittests.
The library now looks inconsistent because I focus mainly on the
features needed in my work. Probably I've made some bad
design/implementation decisions due to lack of experience.
Any ideas and advices are welcome.

What about to post such a good news also in digitalmars.D.announce?
Also, if we are talking about matrices, very sad a solution for
enhancement 6798 [1] isn't merged yet.
