I'm wondering, would it make sense for  `error()` to put exception argument as a cause? For example `error(Exception())` .

What would be the benefit? That's more characters than `throw Exception()`.

I was re-throwing exception, and I accidentally wrote `error(cause)` , so I was wondering, if that could work out of the box

What result would you want? Would it `throw IllegalStateException(cause)` or just `throw cause`? The former seems like an okay suggestion but I'm not so keen on the latter.

I was thinking about former yeah, if you think that makes sense

Unless you add a message argument too, I don't see the point of wrapping the exception. ISE is not particularly specific so it doesn't bring any info

That was just a simple example. The actual exception could have various messages and stacktraces :smile:

It was requested a while ago, but the use case was not clearly described: <https://youtrack.jetbrains.com/issue/KT-55613/Add-a-error-function-that-takes-a-cause>
