I find that logic to be more explicit when living on different lines or is clearly delimited by keywords and spaces. ? has no spaces, it's literally "variable names interrupted by question marks" and evaluation can stop at any time while scanning the line from left to right. Multiple "?" can live on the same line so that's incentive to write one-liners, really, and to me one-liners are always less explicit than the same logic split on multiple lines.
Ah, I see what you mean. Well, think about what actually happens when you write "lst.sort()". In terms of "hidden behaviour", there is far FAR more of it in existing syntax than in the new proposals.
I am not sure I'm following you (what does lst.sort() have to do with "?"?).
Which is back to what Steven said: people demand such a high bar for new syntax that few existing pieces of syntax would pass it.
Probably. That's what happens when a language is mature. Personally I don't think that's a bad thing.
Agreed with Giampaolo. The opportunities for syntax additions should become rarer and rarer. Regards Antoine.
