It doesn't really make any sense to me either. I expect this would continue to be ok: aaa bbb . ccc => (aaa bbb . ccc) And the following would still be an error: aaa bbb . ccc ddd On November 27, 2014 6:04:47 AM EST, "Jörg F.

It would be cool to see sweet and wisp move closer together here!

Re: [Readable-discuss] Discussion: Should leading "." in sweet-expressions have wisp semantics?
Arne can best give the wisp answer, but here is what I would expect: 1.: foo bar . aaa bbb ccc . ddd eee => (foo bar aaa bbb ccc ddd eee) 2.: foo bar . aaa bbb . ccc . ddd eee Error. Period after leading period. Perhaps more interestingly, I would expect this: foo bar aaa bbb ccc . ddd eee fff ggg hhh => (foo bar (aaa bbb ccc) ddd eee fff (ggg hhh)) On November 28, 2014 5:59:14 AM EST, "Jörg F.

It’s the core reason for the existence of the leading-period rule: Making most kinds of general tree/list-of-list structures look similar. I know that that’s not the best description of its effect, but I don’t find a better description right now… I hope you understand what I mean anyway.
