I was more enthused about that, but later I realized there are very few
situations in which one reasonably has a fixed-size array that is large
enough to make counting inadequate and is also updated often enough to
make the feature worthwhile. It's one of those features that are nice to
have but are not really missed in real code.
I am not going to appreciate a language/compiler that accepts and
compiles this program silently. This trap has caused a bug in my code
time ago:
int[3] a = [1, 2];
void main() {}
I've hit that bug many, many times. But...
The usage of [$] in that case avoids that kind of bug...
How? The code above would still compile. Would be much better to just
ban assigning an array literal to an static array of different length.
// It's important that a has a length of 3, so I specify it
int[3] a = [1, 2]
Error: Not enough values for a. Expected 3, got 2
// I don't care what length a has as long as it has a static length
int[$] a = [1, 2];
