In concurrency.d (version 2.055, line 1247 - 1250) , there's some codes related to internal implementation of List(T).
"
Range opSlice()
{
return Range( cast(Node*) &m_first );
}
"
What does this mean? m_first itself is Node *, then &m_first is Node **, then we cast it back to (Node *)? Does it make sense?
If we change "&m_first" to "m_first", it still is weird, because in line 1169:
"
@property bool empty() const
{
return !m_prev.next;
}
"
The list is empty when m_first is null, that is m_prev is null, not m_prev.next is null.
Is my understanding of these codes completely wrong, or it is a bug in the code?
Thanks.
