import std.stdio;

enum { A, B };

/*
If I replace the return type int with enum, doesn't compile.
If I remove the in/body blocks and declare a contractless f, both enum/int are
ok.
*/
int dummy(in int i)
in {
    assert(i > 0);
}
body {
    return A;
}

void main()
{
    immutable x = dummy(0);
}

Maybe you're misreading the runtime assert error as a compiler error?

OTOH if you're trying to declare the return type as 'A', that won't work
because A is not a type.

Unfortunately DMD allows nonsense like this:

enum dummy(in int i) { }

The 'enum' here acts as a placeholder as if you've declared it 'auto'.
