Linked Booleans Logics (rethinking PEP 505)

Ideas
15

I hate to be a party pooper but why are we having this conversation? The original proposal died because:

  • Many people were squeamish about creating a punctuation ridden syntax
  • Nobody could agree on whether some_dict?["missing-key"] should give None or a KeyError (or the attribute-getting equivalents)
  • There were concerns that APIs would evolve to make the need for constant None-awareness more prominent

To propose another punctuation heavy syntax is to miss all the reasons why PEP-505 failed.
