A slightly more fair comparison if we take into account that 'static' acts as
'auto':

-----
void main()
{
    import std.algorithm;
    import std.traits;

    {
        static notEmpty(A)(A a) { return !a.filter!(b => b > 0.0).empty; }
        assert(notEmpty([0.0, 0.0, 0.1]));
    }

    {
        // simpler syntax should be supported
        alias notEmpty = a => a.filter!(b => b > 0.0).empty;
        assert(notEmpty([0.0, 0.0, 0.1]));
    }
}
