Does function overloading not work with nested functions? I got a 
compiler error (something like "function already defined") when I 
tried it.

According to the spec then nested functions cannot be overloaded:

"Nested functions cannot be overloaded."

See: 19.17.1.3

re: documentation. That is one-line tiny footnote in a page 
that's over 85 pages long on my browser. :) I could easily see 
many people missing it until they encounter it.

I agree, I didn't know about it either and only found out because 
I decided to search on the page for functions under nested 
functions.

Correct, it's not allowed.

However, you can define a function template to get effectively 
overloading based on parameter type.

And you can also use an inner struct to define overloaded functions.

I believe templates make a better bandaid
```d
void main(){
	template bar(){
		void bar_(int){}
		void bar_(float){}
		alias bar=bar_;
	}
	bar(1);
	bar(3.14);
}
```

Wow, I never thought of that, it's a great idea! You don't even need to 
use the alias.

```d
void main(){
     template bar(){
         void bar(int){}
         void bar(float){}
     }
     bar(1);
     bar(3.14);
}
