I'm doing very well. Hoping to see you at DConf. :)

That's a good point that comes up regularly. I wonder why C++ code seems 
to use OOP more than e.g. D does? Is it the reverberation of that old 
"everything is an object" style? Otherwise, it's quite possible to do 
compile-time polymorphism in C++ as well.

OT: I've used CMake in an unrelated project. I had failed to learn how 
to write a custom rule in it. It was super easy to make comman targets 
like an executable or library, but not custom stuff that we had needed. 
Anyway... There are smarter people who can use it. :)

OT: Is there something new in Haskell that makes Sieve of Eratosthenes 
easier than the following entertaining paper shows?

Yes, Weka is a great user of D. They take full advantage of the 
compile-time features of D for profit. :)

OT: Unfortunately, I'm not with Weka anymore. :/ Now I know that it 
takes way more focus to work through the 10 hour and the 1 day 
differences. Their weekends are Friday and Saturday, so by the time I 
started my Thursday morning, Israel was already off to their weekends.

Joakim is right when saying "it is hard to market without people either 
trying the language or user testimonials". I'm dealing with the same 
issue at my current job: Despite my attempts, there may be separate 
non-D languages for prototyping and actual implementation.
