T

it just so happens to be that 'static' function variables in D 
require compile-time available initializers. To initialize with a 
runtime value on first execution, you have to implement that 
manually:

void foo(int a)
{
    static int first;
    static first_initialized = false;

    if(!first_initialized)
    {
        first = a;
        first_initialized = true;
    }

    // ...
}
