After scopes, types and signatures we got all the prerequisites to talk about the syntax and semantics of KBOS methods. Unless you want to contribute to Kephra or write a plugin, you may never use them, but please join me in the thought experiment - maybe we get a littler smarter.

There are signatures in Raku, core Perl 5, Moose, Dios and lot of other modules. With KBOS I tried to find out how optimal signatures would look like to me. My objectives are: 3. easy to parse with the eye, 2. concise syntax and 1. delegates as much work as possible into the background so I have to write the least amount of code.
