@ToddAndMargo: These are all explained in the Raku documentation. Long
story short:
"my \t" -- this is a RAW definition. You can use it to hold types, as in

".of" is a method for Parametric Roles. It generally returns a type
"??" is the trinary operator. (expr) ?? <true return> !! <false return>
If you are going to go further, please read the Raku documentation. These
