--- 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.

My example seems to be working now, could be that this has been fixed in 2.082.1.

But I have not yet tested the original example.

Tried it now, seems to work, too.


with the constructor:

this(in float4 arr) {
    vec = arr;
}

the output is correct for both variables.
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?
