I vibe coded a library in Nim the other day (a language I view very much as a spiritual continuation of the Pascal/Modula line), complete with a C ABI.

The language has well defined syntax, strong types, and I turned up the compiler strictness to the max, treat all warnings as errors etc. After a few hours I put the agent aside, committed to git then deleted everything and hand coded some parts from scratch.

I then compared the results. Found one or two bugs in the AI code but honestly, the rest of our differences were “maters of taste” (is a helper function actually justified here or not kind of things).

Yeah actually I worked with Pascal early in my career and that's kinda the vibes I am thinking about, with maybe a stronger type system more ada-esque though (composite, partial and range-and-domain types, all that jazz)
