Hi! Sorry, I was too late to answer that on #raku. The problem here is that when you create a `:model<Something>` Red tries to `use` "Something", on that case `Vmail` but that file does not exist, to fix that you could simply add `:require<Schema>` on that. 
use Red;

model User is table<_user> {
        has Int $!id is serial;
        has Str $.username is column is rw;
        has Str $.password is column{ :nullable } is rw;
        has @.vmails is relationship(*.user_id, :model<Vmail>, :requir
+e<Schema>);
}

model Vmail {
        has Int $!id is serial;
        has Int $!user_id is referencing(*.id, :model<User>, :require<
+Schema>);
        has Str $.name is column;
        has $.user is relationship(*.id, :model<User>, :require<Schema
+>);
}

I'm trying to make it not necessary.
