suggests you can implement a function in a different file, and
a different tutorial somewhere else mentioned the endeavour of
no-bodied-functions as a way of presenting a black-box type of
interface.
This is not a common pattern in d; the only reason it's used in c
and c++ is that those languages don't have a real module system.
However, the way it's done is with .di (d interface) files.
Consider:
test.di:
module test;
void print_stuff();
main.d:
import test;
void main() {
print_stuff();
}
test.d:
module test;
void print_stuff() {
import std.stdio;
writeln("I'm stuff");
}
You can verify the compiler is reading from test.di by putting
test.d in a different directory from main.d and test.di.
