I agree, that looks somewhat ugly. But if you have such short 
functions and short unittest, why not sort them:

```d
auto reduce(alias F,R)(R r)=>r.acc!F.last.front;
auto all(alias F,R)(R r)=>r.map!F.filter!(a=>!a).empty;
auto any(alias F,R)(R r)=> ! r.filter!F.empty;
auto count(R)(R r)=>r.reduce!((a,int b=0)=>b+1);

unittest
{
    assert(counter(10).reduce!((a,int b=0)=>a+b)==45);
    assert([1,3,5,7,9].torange.all!(a=>a%2));
    assert([1,2,3,4,15].torange.any!(a=>a==15));
    assert(counter(10).filter!(a=>a%2).count==5);
}
```

That's pretty much as short as your proposal and even more 
readable.
