It's a shame ucent/cent never got implemented. But couldn't they be added to Phobos? I often need a 128-bit type with better precision than float and double.

I suspect this is more about who the Mathematica and D users are as Project Euler is mostly mathematical rather than code optimization. More of the Mathematica users would have strong maths backgrounds. I haven't felt held back by D at all, it's only been my own lack of ability. I'm in 2nd place atm for D users.

OK, if D is at least BLAS, I will try to overtake you :)

Here and I say that despite the fact that in D BigInt not optimized very well, it helps me to solve a wide range of tasks that do not require high performance, so I want to BLAS or something similar was in D. Something is better than nothing!

FWIW: https://github.com/d-gamedev-team/gfm/blob/master/math/gfm/math/wideint.d

Other things I often have a need for:

Weak references
Queues, stacks, sets
Logging
Custom date/time formatting
Locale-aware number/currency formatting
HMAC (for OAuth)
URI parsing
Sending email (SMTP)
Continuations for std.parallelism.Task
Database connectivity (sounds like this is on the cards)
HTTP listener

+inf for including that into Phobos. current implementations are hacks that may stop working when internals will change, but if it will be in Phobos, it will be always up-to-date.

std.experimental.logger!?

I think the next release of LDC will support it, at least on some platforms...

Perfect, he said sheepishly.
