Is there a good term for "after using this feature we realised that the best design is different from the current design"? In casual conversation I generally hear "bug" but there was nothing wrong with the original implementation.

I've been working on a search tool for a website with 9K items and a dumb implementation works just fine. I'd normally gravitate to a library or tool like elasticsearch (ES). Adding custom filters etc is trivial on handrolled code. I wonder what scale requires actual search infra like ES.

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.
