Is this considered a bug or am I really required to specify that it's an `Int` and not a `Long`?

I guess as soon as you use it (assign it, give it as argument, ...) the ambiguity resolves.

maybe I just hit a rare case :stuck_out_tongue:
```val myString = """hello(value: "something")"""
val invalid = (myString.sumOf { if(it == '"') 1 else 0 } % 2) != 0```

I decided to just make them `Long` 's as it's easier to write an `L`  behind the numbers

I have written a simple parser and was using `sumBy`  but this function has been deprecated, but moving to `sumOf`  brought this issue.

FYI, there is `String.count`, i.e.:
```val invalid = (myString.count { it == '"' } % 2) != 0```
This also resolves the ambiguity :D
