Hi, I need help again. I have an immutable static array and i 
need to initialize its contents inside a for loop. Something 
like this:

void f(int n)(....)
{
immutable float[n] my_array;
for(int i=0;i<n;++i)
  my_array[n]=some calculations(based on constants and n)

...

}

 I'd probably separate the calculations into a separate function, 
and assign the immutable data all at once (which you have to do 
similarly with constructors). So... i think this would work...

void f(int n)(....)
{
  auto static calculate() {
    float[n] tmp;
    for(int i=0;i<n;++i)
      my_array[i]=some calculations(based on constants and n)
    ...
    return cast(immutable) tmp;
  }

immutable float[n] my_array = calculate();
...
}
