Hello all,
I came across some weird behaviors yesterday and I can't figure
out what it's about.
(1)
auto factorial(int n) {
if (n < 2) return 1;
return n * factorial(n-1);
}
The compiler complained about "forward declaration of factorial".
If I change the return type to int, the problem goes away. I can
understand that with the recursion, it might be impossible for
the compiler to deduce the type of factorial and so it compile
errors, but I don't see anything about that on the Language
Reference. Is this the intended behavior?
(2)
auto stuff(T)(T[] arr) {
auto inner(T[] s) {
s[0] = 0;
}
arr.inner();
}
This time the compiler complained about 'inner' not being
defined. This time I have no idea what is wrong.
Thanks for your help!
Michael
