Bug 12770 – Array operation result assignment to static arrays is complicated

I think this should work: float[4] f(float[4] a) { return (-a[])[0..$]; } Error: cannot implicitly convert expression ((-a[])[0..__dollar]) of type float[] to float[4] What I was actually trying to do, is perform array operations on static arrays. I'd like to think this should work: float[4] f(float[4] a) { return -a; } I tend not to think of static arrays like arrays, they're more like a discreet object. Requiring a[] causes a to become a dynamic array, and then it can't be assigned back to a static array anymore. It all goes south for array operations on static arrays with []. At very least, this should probably work: float[4] f(float[4] a) { return -a[]; }
