How to use D for cross platform development?

[Chris W.]

That's all great stuff. Thanks guys. I think in this respect D 
could really take off, i.e. as the natively compiled, portable 
"core language" that can easily interface to platform specific 
frameworks through C and C++. This, among other things, got me 
interested in D in the first place. I think developers are less 
and less willing to re-implement their programs (or portions of 
it) for each platform – especially now that mobile devices add 
yet another array of OSes to the market. It's a question of time, 
money, maintenance and last but not least of trying to avoid more 
work (doing the same thing really).
