I have an issue with the following piece of code:

inline fun StringReader.tryTo(block: StringReader.TryTo.() -> Unit){
	contract {
		callsInPlace(block, kotlin.contracts.InvocationKind.EXACTLY_ONCE)
	}
	try {
		it.block()
	} catch (e: Exception) {
		it.reset()
	}
}

And

override fun parse(reader: StringReader): String? {
	reader.tryTo {
		throw Exception("hi")
	}
	return null // Marked as unreachable code
}

On a inline lambda seems to not realise that an exception that is thrown in the lambda can be caught in the inlined function. This gets even worse when the return is not nullable and the user doesn't add a return as it is marked as unreachable and as a result at runtime the function will return null.

Either it's a bug or the requirements of

callsInPlace

need to be clarified, there's nothing in the docs. Definitely report this on YouTrack.

Ok

And post the link because now I'm interested 😒imple_smile:

Found this in similar issues: https://youtrack.jetbrains.com/issue/KT-26523

If you click the "open command dialog" button on the top left you can type "relates to <id>", I'm not sure if that actually works though, I've never tried that.

It gave a msg like you are not allowed to or something

Makes sense, we aren't allowed to edit most properties of the issues.
