The following code was written for Rosetta Code and is intended to find all
factors of an integer. It produces wrong results. The exact wrong results
depend on whether inlining is enabled.
import std.range, std.algorithm, std.stdio;
auto factors(I)(I num) {
return filter!((i) { return num % i == 0; })(
iota(1, num + 1)
);
}
void main() {
writeln(factors(36));
}
If I change the line with the lambda from a template literal to a delegate
literal:
return filter!((I i) { return num % i == 0; })
then it works.
