Error log, obtained from run.dlang.io

Came across this doing some templated serialisation code and keeping const
correctness.

Does not error with slices.

Code:

void writeThem( T )( ref inout( T ) them )
{
    import std.stdio : writeln;
    import std.conv : to;

    writeln( them.to!string );
}

void main()
{
    const( uint )[4] vals = [ 1, 2, 3, 4 ];
    vals.writeThem;
}
