Is there a name of this kind of function in D? unnamed?
anonymous?
The spec uses "anonymous". Syntactically, `() { ... }` is a
function literal.
There is a section called "Anonymous Functions and Anonymous
Delegates" [1], but it's just a link to "Function Literals":
https://dlang.org/spec/expression.html#function_literals
To be clear, the second set of parentheses in `() { ... } ()`
just calls the anonymous function. You could equivalently write
it like this:
alias f = () { ... };
f();
