Why is TypedReference behind the scenes? It's so fast and safe… almost magical!
...need for this feature internally for interop (e.g. [DllImport("...")] void Foo(__arglist);) and they implemented it in C# for their own use. Design of the CLI is influenced by a lot of languages (annotations "The Common Language Infrastructure Annotated Standard" demonstrate this fact.) Being a suit...
Is a statically-typed full Lisp variant possible?
...here all the cells are of the same type. Lisp happily allows (1 "abc" #\d 'foo). Plus, even if you extend your static-typed lists to cover lists-of-lists, the type of these objects requires that every element of the list is a sublist. How would you represent ((1 2) 3 4) in them?

Pointers vs. values in parameters and return values
...to create your items might force pointers on you, e.g. you have to call NewFoo() *Foo rather than let Go initialize with the zero value.
The desired lifetimes of the items might not all be the same. The whole slice is freed at once; if 99% of the items are no longer useful but you have pointers to t...

How should a model be structured in MVC? [closed]
...b = new Database($conn);
$model = new User($db);
$model->CheckUsername('foo');
