+//
+// This is important for people who monkey-patch `Socket.prototype.connect`
+// since it's not possible to monkey-patch `net.connect` directly (as the core
+// `connect` function is called internally in Node instead of calling the
+// `exports.connect` function).
+//
+// Monkey-patching of `Socket.prototype.connect` is done by - among others -
+// most APM vendors, the async-listener module and the
+// continuation-local-storage module.
