p16. Is there anything other than the random values, unsafe about void
assignment?
I'd put your feedback on my pile of things to do, but now that you ask,
I made this change to the incriminated paragraph:
===========
Such uninitialized arrays are particularly useful for large arrays
that serve as temporary buffers. An uninitialized integral may not
cause too much harm, but uninitialized values of types with
indirections (such as arrays themselves) are unsafe.
===========
p18. What is unsafe about implicit conversion of static to dynamic array?
Meaning getting a dynamic array pointing to a stack allocated
array.
Any operation changing its size could copy the array to the heap.
What am I missing
T[] fun() { T[10] a; return a; }
...
auto x = fun(); // gained access to recycled stack memory
There's no change in size there.
p20. 10 int take up 40 words?
The example given has a per-row payload of 10 ints, i.e. 40 words.
