  • Miško Hevery, IMO a very respectable programmer, has his own opinion about doing real work in constructors. Check his article, that might give you few guidelines. Commented Mar 9, 2017 at 20:29
  • I mentioned this in another comment on one of the responses, but I feel this is not a duplicate; what I am really trying to get at, I guess, is that file handling is something that can fail, but it seems possibly sketchy to have a constructor that can fail. Is this gut feeling correct? I suspect not, because otherwise what would be the point of RAII? Commented Mar 9, 2017 at 23:02
