I haven't read the paper, so I really don't know what problems they see with static if, and C++ _is_ a very different beast than D (particularly with regards to stuff done at compile time), but without statif if, C++ seems very crippled with regards to templates and conditional compilaton. The combination of template constraints and static ifs is _extremely_ powerful in D, and it works very well. C++ currently lacks anything of the sort, and until it does, it's templates will be very much inferior to D's. Maybe they can gain similar power through different mechanisms, but I'm surprised that anyone would think that static if was such a bad idea. It's working fantastically well for us, and I don't know how we'd get along without it. - Jonathan M Davis
