I'm still not sure whether a language should include a "kitchen sink linter" like Rust's clippy or have a package oriented "thousand flowers bloom" linter like eslint for JS and TS. Clippy is delightful out of the box but eslint makes it so easy to have project specific lints.

TIL Tcl has a notion of 'safe interpreters', a mode where you can run untrusted code in a sandbox: https://www.tcl.tk/man/tcl8.4/TclCmd/safe.htm Not many programming languages have this, but it's way safer to include in the implementation than try to build as a userland library.

TIL that C++03 considered a file without a trailing newline to be undefined behaviour! https://stackoverflow.com/a/72377 This was fixed in C++11, but the problem was that #include was a textual operation that could produce invalid syntax if no newline was present.
