Actually, that's what you need to realize in D:

OK, but...
Same thing I can say about BigInt in Phobos.
"And finally `std.bigint` offers good (but not outstanding)
performance."
I decided 17 math problems and for most of them I needed a
`BigInt`:

If in D would not be `BigInt`, I probably would have used to
Boost.Multiprekison on C++:

Or do some slow Python.
Maybe all this and does not give a huge performance, but for a
wide range of mathematical problems it all helps.
Thus, it is better to have something than nothing :) And BLAS is
more than something...
