Using and Writing Go Analyses
summary
Shows how to write a real analyzer using the Analysis API, builds a checker that detects cmp.Equal pointer vs value mismatch by combining the inspect pass with types info, reports precise Diagnostics with source positions, and runs via singlechecker.Main as a standalone check tool. Demonstrates the run function that filters CallExpr nodes, compares argument types, emits an error when types differ, and plugs analyzers into go vet, staticcheck and gopls so the check runs in editors and CI.
