Compile Time Code Weaving in Go, Large Systems Debugging/Profiling
summary
Describes a compile-time AST rewriter called go-weave plus an examples repo (loom) that injects code into binaries rather than at runtime, using generated temp files and go/ast. Demonstrated usages: compile-time code weaving to time every QueryRow across a codebase, log panics from every goroutine, add validations or auth checks, and wrap calls before/after execution; it preserves aspect order, can operate recursively from a root directory, and warns about variable shadowing while offering reference tracking to avoid collisions.
