Create model subset about red

[FCO]

subset isn't a good name once already exists a subset in perl6 that does something completely different

[FCO]

Maybe select! Something like:

Red.select: Track.title.as(“song”), CD.title.as(“album”), Artist.name.as(“artist”);

[FCO]

That could create and return a new anon model with those columns

[FCO]

This anon model shouldn’t be a model, but should do the Red::Result role. Models should do that role too

[FCO]

Person.grep({ .id > 30 }).map: *.name;

was what I was looking for
