Here's an OLD example:

ReturnType!(Fn) glCheck(alias Fn)(ParameterTypeTuple!(Fn) args)
{
    alias ReturnType!(Fn) returnT;

    static if( is( returnT == void ) )
        Fn(args);
    else
        auto result = Fn(args);

    glCheckError();

    static if( !is( returnT == void ) )
        return result;
}

This function is used to wrap OpenGL calls so that error checking is
performed automatically.  Here's what it would look like if we could use
void variables:

ReturnType!(Fn) glCheck(alias Fn)(ParameterTypeTuple!(Fn) args)
{
    auto result = Fn(args);

    glCheckError();

    return result;
}
