About `char` type in STC

Hi all,

       STC can not coerce string with single character to char when passing
parameters, e.g.
```
@groovy.transform.CompileStatic
class Test {
    static s(char delimiter) {}
    
    static void main(String[] args) {
        char a = 'x'   // works
        s(',' as char) // works
        s(',')  // [Static type checking] - Cannot find matching method
Test#s(java.lang.String). 
    }
}

```

        I wonder it is designed on purpose or a bug?

Cheers,
Daniel.Sun

Hi Jochen,

      It is in my TODO list too... Now I will remove the task.
      If somebody could tell me the reason, it would be great...

Cheers,
Daniel.Sun

I recall that being on purpose, sadly I do not recall why.
