P.S. The error message is:
newAA.d(58): Error: slice this.key[] is not mutable
which is odd, because the code reads:
struct Slot
{
Slot *next;
hash_t hash;
Key key;
Value value;
this(K)(hash_t h, K k, Value v, Slot *_next=null) if (keyCompat!K)
{
static if (is(K : Key))
key = k; // line 58
else ...
}
...
}
(This is being instantiated with Key == immutable char[4]).
Why is the assignment being translated into a slice for the assignment?
