Deep dive into the select statement

The select statement is a cornerstone of Go's concurrency model, enabling developers to coordinate multiple channel operations with precision. This talk provides a deep technical exploration of its implementation across Go's compiler and runtime layers. We examine how the compiler transforms high-level select syntax into executable code through IR manipulation, including special-case handling for zero, single, and multi-case scenarios. The runtime implementation reveals a sophisticated selection algorithm featuring randomized polling order, channel locking, and goroutine scheduling mechanics. Come to my talk and gain some insight into how select works under the hood.
