Is there a way to define some functions in the body of a class
definition, and define others outside of it in other places in
the
source file ?
No, there isn't. You have to define all of a class's methods in
the class body.
However, you can define free functions that can be called with
the same syntax as methods using UFCS [1]. For example:
import std.stdio;
class C {
void foo() { writeln("foo"); }
}
void bar(C c) { writeln("bar"); }
void main() {
C c;
c.foo();
c.bar();
}
The main limitation is that, because `bar` is really a free
function and not a method, it will not be inherited by C's child
classes, and therefore cannot be overridden.
