imo Claude Code makes a massive difference. Claude could already write pretty good Nim code ~6 months ago, but Sonnet 4.5 being able to look at Nim compiler errors makes it go 🚀. As a test last week I started to let Claude Code write a small library from scratch too (a LaTeX to MathML conversion lib similar to https://temml.org). It did a perfect job. Didn't write a single line either. My plan was to write that up as a case study and post on the forum. Will do that once I find the time one of these days 🥲
