I'm not sure exactly why this example doesn't work, but it looks like a bug.
Please file.  If you just want to insert a bunch of boilerplate without any
parameters, you probably should try a string mixin instead.  The following does work:

enum string C = q{
    this (int i) {

    }
};

class A {
    mixin(C);

    this () {

    }
}

void main () {
    auto a = new A(3);
}
