There is a big difference between what is allowed from within a package and what is possible in native implementation. As an example - currently this pipe operator seems to be implemented at the parser level. The parser simply takes the pipe expression and translates it into standard nested function call f(g(x)). Which means - there will be almost no cost in speed (%>% was notoriously slow). In addition the user will get the usual error stack in case something within this pipe fails.

I think that symbol is used as an approximation of "lambda" character (λ) on a standard US keyboard.

This is exactly right. It's like saying you solved chess because for each configuration of pieces on the board you can use machine learning to predict whether that position can be achieved with valid chess moves. With 90% accuracy.

Editing should be allowed for an hour or so in order to fix spelling mistakes, reformat text for easier flow, or even as a recovery after pressing "post" by accident. But long-term deleting and editing will hurt the content. This, for example, is visible on reddit where older threads sometimes have these big piles of deleted comments. Instead maybe I would try something new:

1) Ability to post anonymous comments 2) Instead of deleting a comment a user can choose to make it anonymous so that it is no longer associated with his/her account

HN is working fine; different sub-groups segregate under different topics. People who care about Rust comment under threads about Rust, people who care about science-fiction post comments in threads about science-fiction. And people who care about politics post under threads about politics.

Then the question of "why threads about politics usually have lower quality of comments" is left as an exercise for the reader.

These clubs are a bit superficial. I wish there was one with requirements concentrated on user experience rather than technical details.

Maybe "no tracking + no ads + no low-effort content + no clickbait + no paid content" club.

To me it seems like you can have a state of mind, and use that state to predict the state of mind of others without being _aware_ of your state of mind at the same time - that is, without being conscious.
