search for: not_nul

I have to say `not_null(v)` reads more like an assertion than a predicate, in which case `isa<T>(not_null(v))` reads like it has the exact same semantics that `isa<T>(v)` has currently—asserts that `v` is not null. I don't dispute that you can *make* it have the desired semantics, it just won't *look*...

...a T or nullptr", which does not match the implementation semantics "v is a T and not null".

What about a type not_null_impl<T> and we could write: then you could just write bool x = isa<T>(not_null(val)); We provide a function not_null<T> that returns a not_null_impl<T>: template<typename T> not_null_impl<T> not_null(T *t) { return not_null_impl<T>{t}; } and a speciali...

I am currently writing a search method for my rails applications and at the moment it works fine. I have the following in my game.rb: def self.search(search) if search find(:all, :conditions => [''game_name LIKE ? OR genre LIKE ? OR console LIKE ?'', "%#{search}%", "#{search}", "#{search}"]) else find(:all) end end No that searches
