+// Package reuseport provides Listen and Dial functions that set socket
+// options in order to be able to reuse ports. You should only use this
+// package if you know what SO_REUSEADDR and SO_REUSEPORT are.
+//
+// For example:
+//
+//	// listen on the same port. oh yeah.
+//	l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+//	l2, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+//
+//	// dial from the same port. oh yeah.
+//	l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+//	l2, _ := reuse.Listen("tcp", "127.0.0.1:1235")
+//	c, _ := reuse.Dial("tcp", "127.0.0.1:1234", "127.0.0.1:1235")
+//
+// Note: cant dial self because tcp/ip stacks use 4-tuples to identify connections,
+// and doing so would clash.
