What should be considered when deciding whether to declare destructuring functions (e.g. component1()) directly on a class vs. extension functions? AFAIR, when using destructuring extension functions, you need to add the imports manually.

[Matteo Mirk]

I don’t fully understand, sorry: do you mean declaring componentN() functions manually, like the compiler does for data classes?

[Paul Griffith]

IMO positional destructuring is only very rarely a good idea. If you did decide to use it, I would definitely say to just make them member functions so you don’t have to import the extensions

@Paul Griffith There are some useful cases. I like using them from Pair MatchResult.destructured for example. Likewise, there are occasions when I like to declare my own.
