+
+**This requires enabling the `derive` feature flag.**
+
+You can use `--` to escape further arguments.
+
+Let's see what this looks like in the help:
+```console
+$ escaped-positional-derive --help
+clap [..]
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+USAGE:
+    escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...]
+
+ARGS:
+    <SLOP>...    
+
+OPTIONS:
+    -f               
+    -h, --help       Print help information
+    -p <PEAR>        
+    -V, --version    Print version information
+
+```
+
+Here is a baseline without any arguments:
+```console
+$ escaped-positional-derive
+-f used: false
+-p's value: None
+'slops' values: []
+
+```
+
+Notice that we can't pass positional arguments before `--`:
+```console
+$ escaped-positional-derive foo bar
+? failed
+error: Found argument 'foo' which wasn't expected, or isn't valid in this context
+
+USAGE:
+    escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...]
+
+For more information try --help
+
+```
+
+But you can after:
+```console
+$ escaped-positional-derive -f -p=bob -- sloppy slop slop
+-f used: true
+-p's value: Some("bob")
+'slops' values: ["sloppy", "slop", "slop"]
+
+```
+
+As mentioned, the parser will directly pass everything through:
+```console
+$ escaped-positional-derive -- -f -p=bob sloppy slop slop
+-f used: false
+-p's value: None
+'slops' values: ["-f", "-p=bob", "sloppy", "slop", "slop"]
+
+```
