+// function-scope locals)
+// - All functions/classes/etc reside in namespace __esan, except for those
+// declared in esan_interface_internal.h.
+// - Platform-specific files should be used instead of ifdefs (*).
+// - No system headers included in header files (*).
+// - Platform specific headers included only into platform-specific files (*).
+//
+// (*) Except when inlining is critical for performance.
