Why this works:
It's just defined that way. Local functions follow local
variable rules - must be declared before use and names not
allowed to overload each other.
There might be a deeper reason too but like that's the main
thing, they just work like any other local vars.
Overload for local functions will be very useful thing.
Otherwise it is PHP or C.
If you want to define a set of overloaded functions inside
another function, you can do it like this:
void main() {
import std.stdio: writeln;
static struct Overloads {
static void fun(int n) { writeln("int overload"); }
static void fun(string s) { writeln("string overload"); }
}
alias fun = Overloads.fun;
fun(123); // int overload
fun("hello"); // string overload
}
