Anonymous Functions Work like regular functions and do not capture the calling environment. Anonymous functions can use regular or short function syntax. Types may be left out if they can be inferred. import std::io; alias IntCallback = fn int(int x); fn void print3(IntCallback callback) { for (int i = 1; i <= 3; i++) { io::printfn("%d -> %d", i, callback(i)); } } fn void main() { print3(fn int(int x) { return x * x; }); print3(fn(x) => x * x * x); }
