dmd _definitely_ has inlining. It could use some improvement (e.g. functions with lazy parameters can't currently be inlined), but it _does_ have inlining. And dmd's optimizations aren't bad. It's just that they could be better. I expect that we'll see them improve further once the language has stablized more. As much as faster code would be nice, correct code is much more important. And there are still plenty of bugs to iron out in the compiler (though it's definitely improving).

Thank you! That option did the trick. Somehow I didn't see that in the user docs in the gdc site

Building a GDC that does both is still a relatively new development, and I think it hasn't actually been integrated into the main repo yet. Pretty sure whoever's making the Windows binaries (sorry, I should know who that is, but I don't) is patching it before he builds.

Indeed, by lacking I didn't mean lacking the feature, I meant lacking in functionality/ability, there are a lot of things that it could inline but doesn't currently.
