data class MyType(
    /**
     * Information [testing...]
     */
    val field: String,
)

I'm not sure if I have found a Kotlin bug or it's supposed to do this?
But this data class results in a compiler error because of the [testing...] comment.

[stephanmg]

what’s the comma after String?

[crummy]

the comma after string is allowed with Kotlin 1.4.
I repro the behaviour here - I'd guess it's a bug? https://pl.kotl.in/NpY1LuUJx

[jeggy]

That's just using the new functionality from kotlin 1.4.
I'm getting a compiler error both with or without that trailing comma.

The error I'm getting is Closing bracket expected

The error points directly to the ... in the comment also

[stephanmg]

Yeah I can confirm this problem

[stephanmg]

strange.

[jeggy]

I have reported it as a bug here: https://youtrack.jetbrains.com/issue/KT-45516

Just not sure if it is actually a bug or it is a requirement from Kotlin to have valid references within the [] in comments.

[stephanmg]

Well, the error message is at least not helpful then if this should be the case

[stephanmg]

@jeggy just curious

[stephanmg]

does it work if you remove the three dots (…)?

[jeggy]

as long as there is 1 . it breaks

[stephanmg]

haha ok

[stephanmg]

looks like a lexing issue

[jeggy]

but if you have anything after the . then it works again

[stephanmg]

haha ok

some jetbrains dev is definitely going to have fun with this one 🙂

(not meant sarcastically)

[jeggy]

Was just surprised when my code failed and the error pointed to a comment 😆

[Nir]

all you need to do is leave a comment showing the code that crashes the compiler, so the next guy knows why it's that way

[Nir]

wait a second...

[TwoClocks]

does the new IR compiler generate the same error?
