As the code below shows, dmd doesn't compile well when a lambda function is
nested another lambda(only fails if the result is used somehow later).

test case:
===========
module foo;
import std.algorithm, std.range, std.array;

auto bar()
{
    auto data = [5, 6, 7, 8],
        test = map!( (x) => reduce!"a+b"(data[$-x..$]) )([1, 3]);
    return array(test); // or "wrilteln(test);". if just "return test;" it
works.
}
==========

When compile this module without -inline, it works. Otherwise it will be
failed:
foo.d(7): Error: function foo.bar is a nested function and cannot be accessed
from std.array.array!(MapResult!(__lambda2,int[])).array
