Are hyphens/dashes not allowed in subcommand names?

[frumioj]

I wanted to specify a subcommand containing a dash (-). When I do that, the macro version of clap gives me a compile error:

The apparently actually offensive line (I only know by changing the line back and forth - the error was not explanatory) is:

   (@subcommand list-slots =>

And the compile error from rustc is:

60 | let matches = clap_app!(myapp =>
| ___________________^
61 | | (version: "1.0")
62 | | (author: "John K. ")
63 | | (about: "Fabulous cli app")
... |
72 | | )
73 | | )
| |_____^ no rules expected this token in macro call

Is this expected behaviour (by the developers)?

Try "list-slots"
