* A CodeArgument must be the final argument of the command. Once all options

* and other arguments are used, any remaining input until the end of the string
|

|
21 |

* escaping, etc.
|

|
|
|
25 |
*
|
|
|
26 |
* parse function() { return "wheee\n"; }
|
|
|
27 |
*
|
|
|
28 |
* ... without having to put the code in a quoted string and escape everything.
