The thing I'm trying to implement is: I have a function 
foo(string s)() and some "state"; this function should override 
this "state" (using "s" param) for all code within this 
function (note that code can execute other modules that can 
refer to the same "state"). The problem is that I need this 
overridden "state" to be compile-time constant to be used in 
mixin. Any ideas how I can do this?

In regular code it should look like this:
private string[] state;

string getCurrentState()
{
  return state[$-1];
}

void foo(string s)
{
  state ~= s;
  scope(exit) state = state[0..$-1];

  ...
