In this case you would need to use cast(bool) like this:
```d
auto and(T,U)(T value1, U value2) => (cast(bool)value1) && 
(cast(bool)value2);
```
because int does not automatically cast to bool.

Using Steve‘s code, for example:

```d
bool and(bool a, bool b) => a && b;

void main() {
    int foo, bar = 1;

    if(foo.and(bar)) { }
}
```


Anyway, the original request was not about UFCS functions.
The codes are just something to play with, playing with ideas. 
Nothing useful. ;)
