Caller is *ssa.Function. Its Pkg field is *ssa.Package. But ssa.Package struct doesn't contain either field or method named Object. So one gets the following error: $ callgraph -format '{{.Caller.Pkg.Object.Path}} -> {{.Callee.Pkg.Object.Path}}' \ $(go env GOROOT)/src/net/http/triv.go | sort | uniq callgraph: template: -format:1:9: executing "-format" at <.Caller.Pkg.Object.P...>: can't evaluate field Object in type *ssa.Package ssa.Package contains Pkg field: Pkg *types.Package // the corresponding go/types.Package types.Package contains Path() method that returns the package path. That appears to be the right way to get the "import path of the enclosing package" with the current x/tools/go/ssa API. Fixes golang/go#20459.
