Context receivers seem to be extremely useful when dealing with transformations that should be done under a

memscoped

block.

context (NativePlacement)
internal fun LPWSTR.toLatin1Buffer(): LPSTR {
  val latin1BufferSize = WideCharToMultiByte(28591u /* ISO-8859-1 */, 0u, this@toLatin1Buffer, 0, null, 0, null, null)
  val latin1buffer = allocArray<CHARVar>(latin1BufferSize)
  WideCharToMultiByte(28591u /* ISO-8859-1 */, 0u, this@toLatin1Buffer, 0, latin1buffer, 0, null, null)
  return latin1buffer
}

IMO, yes and no, because you will always think, that you can easily/safely move

NativePlacement

to context receiver and then, in this case you can accidentally be trapped in a situation when you create single

MemScope

block for whole application - and so it will be never actually cleared So, that' a good use case, but for me it's dangerous - but may be Im overreacting 🙂
