I have trouble with mixin templates too. I believe the effect you see is
because the mixin introduces its own scope and you have to qualify
reference that are outside the mixin.

However, the new mixin(Statement) might be useful to you ...

-------------
import std.stdio;
class SomeClass
{
     int memberVar;
     void doSomething()
     {
        int localVar;
        mixin(helperFunction);
        helperFunction();
     }
}

const char[] helperFunction = "
     void helperFunction()
     {
         localVar++;
         memberVar++;
     }
    "; 
void main()
{
    SomeClass x = new SomeClass();
    x.doSomething();
    writefln("memberVar = %s", x.memberVar);
    x.doSomething();
    writefln("memberVar = %s", x.memberVar);
}
