Not by mistake, but intentionally because I want to pass a 
formatted string to my function.

And if I'm not mistaken, that string will be expanded into a 
tuple that could mess up the call to my function, returning an 
error that might confuse the user. In the worst case, it could 
call my function with extra parameters I didn't even expect, 
causing some unexpected side-effects.

```
// This function delete all the file passed (just a joke)
void deleteFiles(string[]... files) { ... }

// Example
deleteFiles("/tmp/test.txt", "/tmp/old.txt");
deleteFiles(i"/tmp/$dirname/$file"); <-- ooops this will be 
expanded?
```
