Beside praying and pestering, what can we D non-experts do to help get a stable 64-bit dmd available?
Killer D features are strings, slick built in dynamics arrays, no headers files to keep in sync, and the other nice features often praised by others. I'm not sure yet that D is my favorite language, but it's in the list of top three. Killing D (at least for me) is the limit choices for compiling on 64-bit Linux with D2 and preferably Phobos instead of Tango. My setup, for reasons I haven't investigated deeply, can't run 32-bit anything, and I do intend to work on huge arrays of data, a few GB in RAM. As for Phobos, it's obviously more Mars-related than "Tango" :)
