Example: import std; void myfun(int n){ writeln(n); } void test(lazy void delegate() fun) // how specify that "fun" may receive int ? { fun(int); } test({myfun;});You need to change signature of your function to: ``` void test(lazy void delegate(int) fun) /// ^ this is all you need :D ``` And then pass some value to `fun` Working example: https://run.dlang.io/is/B9bbVl
