and how about access to class fields? manual mangling is a half-working
hack. alas. i really want to have some normal and non-hackish way to
separate class definition and class implementation. besides, your trick
is faulty, 'cause it misses hidden 'this' parameter. try that:
// methodLink.d
class A { void foo(int n); }
void main () { auto a = new A; a.foo(42); }
// missingMethod.d
import methodLink;
import std.stdio;
pragma(mangle, A.foo.mangleof)
void foo(int n) { writeln("n=", n); }
it writes gibberish and segfaults.
