Earlier this summer, the Go team released version v0.12 of gopls, the language server for Go, featuring a rewrite of its core that allows it to scale to larger codebases.
Since then, we've fine-tuned the design, focusing on making interactive queries as fast as they were with v0.11, despite holding less state in memory.

This data structure is used in #golang source code (mainly inside the compiler).
I came up with another idea that can work even faster:
