Has anyone already thought about private imports. They can be useful when we want a module to import another one, but don't want this module to import any symbols in the module that import it.

Here is an example:

--- tokenization.d ---
private import ctype;

Token[] toTokens(char[] source)
{ /* code which use ctype's functions */ }

--- main.d ---
import tokenization;

int main()
{ /* code which use toTokens() */ }

So if the main module wants to use ctype's functions it have to import ctype itself. This will cause the user to have less chances to make ambiguity mistakes.

The fewer symbols are valid in a module the fewer ambiguity errors the
programmer will get.
The fewer errors the programmer will get the more easier programming will be
(IMO, ambiguity errors are usually frustrating because they can be boring to
correct).

It's a good idea.
