Sorry, the 'for' should be 'foreach'.
The standard library std.algorithm is based on Range. So if
a = [1, 2, 3, 4];
auto r = filter!("a < 2")(a);
Here, r is a range.
How about I want an new array? Is there any easy way to convert the
result to array?
If we have to do like:
int[] b;
for (v; r) {
b ~= v;
}
Then maybe it is easier

How could it be? It's specific to the template that you're testing.

Also by static function you probably mean private in D.
No, I meant for mixin I nead static functions, but I just realized,
it also works without the static keyword.
I think static has no meaning in global scope, only in function scope
where it tells the compiler you don't want a closure.
