alias & local function

[Alain De Vos]

This one runs fine,
```
import std.stdio;
void main()
{
		static int Gfunction(int x){return x;}
		int Lfunction(int x){return x;}
		alias gfunction = int function(int);
		alias lfunction = int delegate(int);
		gfunction g = & Gfunction;
		lfunction l = & Lfunction;
		writeln(g(1));
		writeln(l(1));
}

```
