It's quite possible. All you have to do is make a
module, which
doesn't
contain any function bodies. The imported modules aren't
compiled with the
code. Most of the time it's easier to have a single
module to
have both the
code to compile and symbols to import. In other cases
they can
be separated.
Okay, so it works just like in C:
// The "header" file
module lib;
void printHelloWorld();
// The "source" file
module lib
import std.stdio;
void printHelloWorld() {
writeln("Hello world!");
}
Exactly. Not defining a function body is perfectly fine for
precisely
these reasons. And, just like in C, forgetting to link with
the missing
body will result in a linker error.

The compiler can even generate those files for using the -H
option. It will generate .di files. Although any formatting
will get lost during that process.

All right, thank you for the clarification.
