Does DUB create .dll files?

I just incorporated DerelictALURE into a project and it compiled and linked fine, but when I ran the executable, it aborted with: derelict.util.exception.SharedLibLoadException@N:\DUB_Packages\DerelictOrg\DerelictUtil\source\derelict\util\exception.d(35): Failed to load one or more

Re: `return ref`, DIP25, and struct/class lifetimes

There is also another counter-obvious bit regarding current implementation - it only tracks lifetime of actual references. Check this example: ref int wrap ( return ref int input ) { return input; } int badWrapper() { int z; { int x = 42; z = wrap(x); }

Hi all! Let's talk about void pointers a little bit. Found this already http://forum.dlang.org/thread/codoixfeqstvqswir...@forum.dlang.org?page=1 but my question/problem differs from the above, so maybe, I have found a useful application for void pointers... Form of the posting: I have some
