A small problem in the module system.
To see this problem you need 3 source files, named test1.d, mod1.d, mod2.d:

-----------------

module mod1;
import std.string: join;
import std.string: join;

-----------------

module mod2;
import std.string: join;

-----------------

The main module is test1.d:

module test1;
import mod1, mod2;
void main() {
    join(["a"], "");
}

-----------------

Got, DMD output:
test1.d(4): Error: mod1.join at mod1.d(2) conflicts with mod2.join at mod2.d(2)

Expected:
No errors, or an error in mod1 of duplicated import statement.

Note: in real code with many imports it's easy enough to import two times the
same name from the same module.

cat > mod1.d << CODE
module mod1;
import std.string: join;
import std.string: join;
CODE

cat > mod2.d << CODE
module mod2;
import std.string: join;
CODE

cat > test1.d << CODE
module test1;
import mod1, mod2;
void main() {
    join(["a"], "");
}
CODE

dmd -c test1.d

-------
mod1.d(2): Error: alias mod1.join conflicts with alias mod1.join at mod1.d(3)
                                                          ^--- mod1

It's complaining about:
import std.string: join;
import std.string: join;
