Issue: #47
Pull request: #48
Contributed by @peter-gribanov

Example:

class CommandAction extends Enum
{
    const EDIT = 'edit';
}

class AccessRule extends Enum
{
    const EDIT = 'edit';
}

Expected

CommandAction::EDIT()->equals(AccessRule::EDIT()); // false

Actual

CommandAction::EDIT()->equals(AccessRule::EDIT()); // true
