https://issues.dlang.org/show_bug.cgi?id=15956 --- Comment #1 from joeks@mail.de --- As far as I can tell this problem stems from the fact, that some of the types in core.simd are not working AT ALL. Consider this simple example: double4 f; f[0] = 1.0; f[1] = 2.0; f[2] = 3.0; f[3] = 4.0; writeln(f); This outputs: [1, 2, 0, 6.95325e-310] I wonder has noone ever tried to use this type in any program or did not notice this obviously completely wrong result? -- |

Edit: Does work correctly with gdc. -- |

But I have not yet tested the original example. -- |

However the compile error with the float[4] accepting constructor is is still there. Also it did not matter if the 'if anything' was present or not. I suppose this is a different issue (or a feature?) and should therefore be addressed in a different thread. -> This can be closed? -- |
