+// This file and importx_test.go make it possible to write tests in the runtime
+// package, which is generally more convenient for testing runtime internals.
+// For tests that mostly touch public APIs, it's generally easier to write them
+// in the runtime_test package and export any runtime internals via
+// export_test.go.
+//
+// There are a few limitations on runtime package tests that this bridges:
+//
+// 1. Tests use the signature "XTest<name>(t TestingT)". Since runtime can't import
+// testing, test functions can't use testing.T, so instead we have the T
+// interface, which *testing.T satisfies. And we start names with "XTest"
+// because otherwise go test will complain about Test functions with the wrong
+// signature. To actually expose these as test functions, this file contains
+// trivial wrappers.
+//
+// 2. Runtime package tests can't directly import other std packages, so we
+// inject any necessary functions from std.
+
+// TODO: Generate this
