Mochi v0.10.5: A LINQ-style query language with a bytecode VM written in Go

We’ve been building Mochi, a small statically typed language for querying structured data like JSON, CSV, and in-memory lists. In the latest release (v0.10.5), you can write SQL/LINQ-style queries with from, where, join, and group by, all fully type-checked and testable inline.

What makes it different: queries compile to a register-based bytecode VM (written in Go) with compiler passes like constant folding, liveness analysis, and dead code elimination. It’s meant to feel like writing SQL inside a real language, backed by actual compiler infrastructure.

If you’re interested in how query engines, DSLs, or virtual machines work, this might be worth exploring.
