With regards to the 'assert blocks' you mention, D (like C++) has 
both static assert and runtime assert.

// ---
module test;
@safe:

import std;

void main()
{
   string val = "some string";
   static assert(is(typeof(x) : int)); // assertion fails at 
compile time.
   assert(val == "some other string"); // assertion fails at 
runtime.
}
