Python cryptography, Rust, and Gentoo

Maybe not. These are not things that I think any one person's view is going to give the same size and scope for any individual feature as another's view anyways. Personally, these are not "small" things to be adding to C++ (in aggregate).

Pattern matching, at least, adds a decent amount of syntax to the language. Contracts does too (though, thankfully, both are via context-sensitive keywords). Template-this also has some additional syntax (though that feels like a cleanup at least).

Modularized stdlib probably is going to have knock-on effects for projects not using IWYU where types aren't leaking out over entire #include trees.

I'm also aware of the scope of modules pretty intimately: I'm working with the ISO committee to make sure they can be built at all :) .
