Re: Wrong vtable for COM interfaces that don't inherit IUnknown

Primary consumer of COM interfaces is Visual Basic. It was really only Bill Gates who loved Basic, he wrote a Basic interpreter in 1975 and created Microsoft as a business that sold Basic interpreters. As gamedev was locked in C++, there was no real use case for COM there, so MS probably does the expected thing and goes with straight C++.
Re: OT: in economic terms Moore's Law is already dead
TBH modern computers are obscenely powerful, I just spent weeks on celeron 1.8GHz 2mb L2 cache 2gb ram computer and didn't see any slowness on it despite some bloated software in python and a strange text editor pluma that ate 150mb ram just editing a plain text file, I swear it's not based on electron, most operations were seemingly io-bound. On my notebook I downclocked i7 to 50% to reduce it to a decent TDP, there was a reduction in performance... probably, because I don't see it without reference, i7 was a mistake, honestly.

Those make this easy without any mixin or wrappers/casts at all. But even if you did want to do the mixin route, look at how Phobos does this. http://dpldocs.info/experimental-docs/std.traits.SetFunctionAttributes.1.html the example of that function shows adding pure to a function pointer. (and btw I think the phobos function itself works with -betterC as well, you might be able to simply call it). Thanks your all for explain, now i get a better understand how pure & debug & nothrow to work together.

But then look at its implementation too: http://dpldocs.info/experimental-docs/source/std.traits.d.html#L2354 .stringof only appears once there, for the `static assert` error message. Everything else is direct stuff. It does string concat a list of keywords, but they are literally written. Then, it immediately mixes it in and thus the template returns the generated type which is used to make an alias and a cast on the outside, avoiding any mixin there too.
Moving location of dub packages?
I'd like to move where dub has stored packages to a shorter path, is there a procedure for this? Thanks in advance!
