I originally implemented it that way and had that exact same issue (it's one of the revisions on github). Similarly, {/} would also be a problem.

  How about {,} or s{} ?
  - philipbjorge 14y ago
    I didn't think to do {,} which I like. s{} looks weird to me, but I couldn't tell you why.
    - digisign 14y ago
      The s{} alternatve is based on the strange r'' or u'' syntax i've gotten used to.

    I think {,} is intuitive because it reminds me of syntax for one-element tuples, e.g. (1,) -- but it may make code harder to read, which is not Pythonic.

Wouldn't it lead to the same problem of a lack of consistency? dict: {} list: [] tuple: () set: {-}
