I'd like something like that:
alternative names would be:
__function__
__context__

----
auto fun(alias caller=__function__)(){
  //caller represents fun1!double
  return ReturnType!caller.init;
}

T fun1(T)(T x){
  assert(__function__.stringof==__FUNCTION__);
  alias fun=__function__;
  assert( is(ReturnType! __function__) == T);
  return fun();
}
void main(){fun1!double();}

I don't think you can pass it in to the function, but you can use 
__traits(parent) on a variable within the function to get the 
function.
