+# go-nul
+
+Package **nul** implements a **nullable** **optional-type**, for the Go programming language.
+
+In other programming languages, an **optional-type** might be know as: a **option-type**, or a **maybe-type**.
+
+## Documention
+
+Online documentation, which includes examples, can be found at: http://godoc.org/sourcecode.social/reiver/go-nul

+[![GoDoc](https://godoc.org/sourcecode.social/reiver/go-nul?status.svg)](https://godoc.org/sourcecode.social/reiver/go-nul)
+
+## Examples
+
+Here is an example **nullable** **optional-type** that can hold a string:
+```go
+import "sourcecode.social/reiver/go-nul"
+
+//
+
+var op nul.Optional[string] // the default value is nothing.
+
+// ...
+
+if nul.Nothing[string]() == op {
+	fmt.Println("nothing")
+}
+
+// ...
+
+op = nul.Null[string]()
+
+// ...
+
+if nul.Null[string]() == op {
+	fmt.Println("null")
+}
+
+// ...
+
+op = nul.Something("Hello world! 👾")
+
+// ...
+
+switch op {
+case op.Nothing[string]():
+	//@TODO
+case op.Null[string]():
+	//@TODO
+case op.Something("apple"):
+	//@TODO
+case op.Something("banana"):
+	//@TODO
+case op.Something("cherry"):
+	//@TODO
+default:
+	//@TODO
+}
+
+// ...
+
+value, found := op.Get()
+if found {
+	fmt.Println("VALUE:", value)
+} else {
+	fmt.Println("either nothing or null")
+}
+```
