std.format.formattedRead and File.readln()

[Eyyub]

Hi,

This following code won't compile :

import std.stdio;
import std.format;

void main()
{
	auto f = File("myfile.txt", "r");
	uint life;
         formattedRead(f.readln(), "Life %s", &life); // Error 1
         formattedRead(cast(string)f.readln(), "Life %s", &life); 
// Error 1
	string str = f.readln();
         formattedRead(str, "Life %s", &life); // works
	writeln(life);			
}

Error 1 :
Error: template std.format.formattedRead does not match any 
function
template declaration

C:\D\dmd2\windows\bin\..\..\src\phobos\std\format.d(502): Error: 
template std.fo
rmat.formattedRead(R,Char,S...) cannot deduce template function 
from argument ty
pes !()(string,string,uint*)

Even more weird :

import std.stdio;
import std.format;

void main()
{
	auto f = File("myfile.txt", "r");
	uint life;
         formattedRead(f.readln(), "Life %s", &life); // Error 1
	writeln(typeid(f.readln())); // Error 2 O_o			
}

However :

void main()
{
	auto f = File("myfile.txt", "r");
	writeln(typeid(f.readln())); // works fine			
}

Error 1 && 2(sorry):

Any reactions ? :D

Thanks !
