Remove an old workaround that was kept around for ABI-compatibility on x86-64 between different LLVM versions. This means LLVM r67588 is required if you want to compile for x86-64, otherwise the backend will assert when you try to return e.g. struct { int i; char c; } from a function. (In particular, this is no longer compatible with LLVM 2.5) It also means that any code returning small structs on x86-64 will probably need to be recompiled in order to be linkable to code compiled with this change.

alias char[] string;
template Unstatic(T) { alias T Unstatic; }
template Unstatic(T: T[]) { alias T[] Unstatic; }
template StupleMembers(T...) {
  static if (T.length) {
      const int id=T[0..$-1].length;
      const string str=StupleMembers!(T[0..$-1]).str~"Unstatic!(T["~id.stringof~"]) _"~id.stringof~"; ";
  } else const string str="";
}

struct Stuple(T...) {
 mixin(StupleMembers!(T).str);
}     
Stuple!(string, void delegate(float)) foo;
