Basically, this fails:
//----
void main()
{
    void foo();
    void foo(int);
}
//----
Error: declaration foo is already defined
//----

I *think* this is according to spec? However, I find this behavior unrational,
since you can get it to work with a simple wrap:

//----
void main()
{
    static struct S
    {
        static void foo();
        static void foo(int);
    }
    alias foo = S.foo;
}
//----
Fine! No problem!
//----

Given that the second example compiles, I think the D language should allow
local function overloading.

...

Or, if the issue is one of scope/context/forwardreferences (?) to at least
allow overloading of static local functions, eg:

//----
void main()
{
    static void foo();
    static void foo(int);
}
//----
