A decimal.js Go port turns up bugs in the original

The piece to sit with is a writeup on porting decimal.js to Go over 72 hours, which quietly surfaced two real bugs in the original library. Around it, a proposal lands to add IsASCII to strings and bytes, and a Reddit thread picks at the accept-interfaces-return-concrete-types idiom to ask the less-answered question of when the concrete return should be a value versus a pointer. Elsewhere, someone reports agentic code review mostly catching their agent writing Java in Go, which sounds about right.
