we won't find that there is a definition for it with just two
parameters, so from where you got this new definition of this
function?!
This thread is about
[UFCS](https://tour.dlang.org/tour/en/gems/uniform-function-call-syntax-ufcs). It can also be written as:
```d
import std.string,
std.stdio;
void findStr(string str) { }
void main()
{
string str = "Hello, World!";
str.indexOf("Wo").writeln; //7
auto pos = "Hello, World!".indexOf("Wo");
auto slice = str[pos..$-1];
slice.writeln(": ", slice.length); // World: 5
typeid(slice).writeln; // immutable(char)[]
assert(str.indexOf("Wo") == pos);
void find_str(string str) { }
find_str(str);
str.findStr();
/* No compile:
slice.typeid().writeln;
slice.indedOf("Wo").assert();
str.find_str();
*/
}
```
