this idiom for creating static array used to work, but they are failing
What changed and whats the alternative?
T[n] s(T, size_t n)(auto ref T[n] array) pure nothrow @nogc @safe
void main() @nogc
int myDynamicArray = [1, 2, 3].s; // Slice that static array
which is on stack
Deprecation: slice of static array temporary returned by s([1, 2, 3])
assigned to longer lived variable myDynamicArray
auto myStaticArray = [1,2,3].s;
Now use it anywhere you need dynamic arrays as myStaticArray. A lot of
times, it will work without having to slice it.
What you are being told is that your memory is not being kept around.
Essentially what you had originally was a memory corruption bug (yes,
even before the deprecation happened). Don't do that anymore!
Note to ponce, please update your idioms, this is NOT safe, even within
the same function. Just because it does work, doesn't mean it will
always work. The language makes no guarantees once the lifetime is over.
