Pure doesn't consider shared variables accessed by other threads.
In this sense m_fill is like a global variable even though local to the
circular buffer struct and the implicit this parameter.

struct SCircularBuffer
    shared ℕ m_fill = 0;

     property ℕ availableBytesForReading() const pure nothrow
        return atomicLoad(m_fill);
