Re: Explain function syntax

[Ali Çehreli via Digitalmars-d-learn]

As stated by multiple people, most nested functions will be 'delegates'. 
However, a nested function is a 'function' if it does not touch local scope:

void main() {
    int twice(int i) {
        return i * 2;
    }
    // Not a delegate:
    static assert(is (typeof(twice) == function));
}
