import std.stdio, core.simd;
void main() {
    ubyte16 x;
    writeln(x); // Error
}


DMD 2.064alpha gives a long sequence of errors:

...\format.d(2950): Error: template std.format.formatValue does not match any
function template declaration. Candidates are:
...
test.d(4): Error: template instance std.stdio.writeln!(__vector(ubyte[16u]))
error instantiating


The workaround is to use .array:

writeln(x.array); // OK

But I'd like writeln to write SIMD values as ubyte16 even without .array for
greater uniformity in debugging code.
