So.. Every method you call through a const instance must also
be const, otherwise you have the ability to change something

First, AFAIK, there is no equivalent of C# readonly in D,
despite the fact that D uses 3 keywords for various kinds of
immutability.
Second, here you can find a mocking library for D:

If all (but last of) the dimensions are known at compile time,
then you can dynamically allocate an array of fixed sized
arrays:
//
enum size_t gridSize = 4_000;
enum size_t total = gridSize * gridSize;
static assert (total == 16_000_000); //16 million doubles total

It's it cute when you use a language almost daily for few years,

Right, because you are duplicating the string onto the heap, and making

I thought druntime always created dynamic arrays on the heap and returned

Hi,
In phobos there are places with void[] and places with ubyte[],
and I can't really understand why there is this difference. I
don't even see why D has a void array or void pointer anyway.
For example, in std.base64, ubyte[] is used as the basic quantity
for encoding, while in std.zlib,

He can still read a chunk from the file, or the whole file and then read
