continue int fibonacci() {
int a = 0, b = 1;
while (1) {
yield(a += b);
yield(b += a);
}
}
int main() {
function fib = fibonacci();
while (1) {
write("--> %d\n", fib());
sleep(0.125);
}
}
In theory, this should yield a stream of Fibonacci numbers (1, 1, 2,
3, 5, 8, 13, etc). In practice - on Pike 8.1.14 - it yields counting
numbers (1, 2, 3, 4, 5, etc). I've tried to defeat the optimization in
a few ways but to no avail. The only way to get Fibonacci numbers out
of it is to avoid yield altogether:
#define yield(x) write("%d\n", x)
Any ideas?
