Hello, I've been reading over an interesting Answer on StackOverflow by wamba:
https://stackoverflow.com/a/67324175/7270649 I started trying to explore enums on my own and quickly realized that method calls on enums are different from simple key/value pairs. For enums, calling a `.key` or `.value` or `.kv` method won't work. Instead one must use something like `.^enum_values` or `.^enum_value_list`. Can someone explain how `.^enum_values` or `.^enum_value_list` came to be the **correct** incantation for enums, and why there is no equivalent `.^enum_keys` or `.^enum_key_list` commands? Thank you, Bill. > # In the Raku REPL (wamba's enum example 'Month') > enum Month (jan => 1, |<feb mar apr may jun jul aug sep oct nov dec>); Map.new((apr => 4, aug => 8, dec => 12, feb => 2, jan => 1, jul => 7, jun => 6, mar => 3, may => 5, nov => 11, oct => 10, sep => 9)) > > Month.^enum_values {apr => 4, aug => 8, dec => 12, feb => 2, jan => 1, jul => 7, jun => 6, mar => 3, may => 5, nov => 11, oct => 10, sep => 9} > Month.^enum_value_list (jan feb mar apr may jun jul aug sep oct nov dec) > > Month.^enum_keys No such method 'enum_keys' for invocant of type 'Perl6::Metamodel::EnumHOW' in block <unit> at <unknown file> line 4 > Month.^enum_key_list No such method 'enum_key_list' for invocant of type 'Perl6::Metamodel::EnumHOW' in block <unit> at <unknown file> line 1 > > #Random keyword attempts: > Month.key Invocant of method 'key' must be an object instance of type 'Mu', not a type object of type 'Month'.
