I disagree. It is arguable whether having > enum Databases { MySQL, Postgres, Oracle } > enum Colors { Red, Green, Blue } > > database_select(Colors::Red, $sql); should give an error for a Databases type hint on the first parameter, as it can be converted (that's a soft vs strict typing issue). However, such typehint should avoid a call like: > database_select(1024, $sql); with which the function can't do anything sensible with (other than returning an error if it does its own checking).
