Expr

io.eezo.db.Expr
See theExpr companion object
enum Expr[T]

A predicate over T, as the small closed ADT BACKLOG §7 asks for. DESIGN §9.2.

Values never reach the SQL string: each becomes a ? and a Bind that goes through the same Column[A] the macro summoned for encode. Injection is not defended against here, it is unrepresentable.
