I finally found the bit where it describes associative array literals

Is there a way to get use constructors with traits functions that take a
function? For instance, functionAttributes!(func) takes a func and tells you
whether it's pure, nothrow, etc. However, giving it the type doesn't work (i.e.
functionAttributes!T), and giving it this doesn't work (i.e.

First, you can't forward-declare classes in one file that are defined in

There seems to be 2 main differences between structs classes:
1. structs instances are direct values, implement value semantics; while class
instances are referenced (actually pointed)
2. classes can be subtyped/subclassed in a simple way; structs cannot be really

a value makes no sense by itself, it is bound to what it describes an aspect
of; referencing a value is meaningless, only copy makes no sense. For
instance, the position color of a visual form should be values.
Structs may have a meaning by themselves, all kind of member functions,

You may use a cast(). If it return null then it's not castable.
Also, I would

we may want to use structs for fast creation, but if ever they mean

Hello bearophile,
In a not-ranged cases body, like in the program below (that doesn't
compile), the switch variable is a compile-time constant, so why
doesn't the compile see x as constant there?

static if (x = 1)
enum Foo = 1;
else
enum Foo = x * Foo!(x - 1);

I copied a module because I am changing its form. The original is still

I only knew the answer because I had almost exactly the same bug a week
