Add packages (like the same in Java/Python/etc).
Package definition and import:

/*main.???*/
import std::vector
import std::iostream

import utils::local_strings

int main(int argc, char** argv) {
    std::cout << utils::local_hello_world("wuki") << std::endl;
}

/*utils/local_strings.???*/
package  utils
import std::string
import std::utils
string local_hello_world(string locale){
.....
    make_pair("wuki", "ahr-ahrrrr")
......
}

Package determained by the file system, so line with "packege" may be
ommited. Package system works like it creates 2 (imagine) files from
original: *.h and *.cpp and include *.h one instead of import. Also package
means that code encapsulated into namespace.

For packages may use *.cpp files. In this case "package" word is a
directive to process this file like package file.

Structure of imagine *.h file:
1. own includes
2. forward declarations/typedefs
3. extern declaration
4. templates(realization)

So we have 2 question:
1. How to order forward declarations/typedefs
a) We can leave it as it is (remains errors with incompetible types).
b) Regroup to avoid any errors with incomplete types (occurse error with
recursive declarations).
As for me, the firs way is prefered because it simpler and can be improve
to  second.
2. What declarations need to be shared(extern)
a) Any non-static varible
b) extend public and private keyword on package and create 2 imagine *.h
files - for package and for external usage

Did you read first the proposals for Modules?
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3347.pdf

There is an ongoing implementation in Clang, see

A google search will give you more.
