Hi,
I have a class that implements a lot of interfaces and I would like to
separate the definition into different files, i.e. implementation of one
interface in one file. Something akin to this C++ code:

a.cpp:

class A
{
  void b();
  void c();
};

b.cpp:

void A::b() {}

c.cpp:

void A::c() {}

Is there a way to do it in D easily? Do I have to use UFCS?

Thanks,
Martin

D has interface files, .di. These can be automatically generated by the  
compiler using the -H switch.

So you code your class normally:
a.d:
class A
{
    void a() {}
    void b() {}
}

$ dmd -H a.d
$ cat a.di
// D import file generated from 'a.d'
class A
{
    void a()
{
}
    void b()
{
}
}
