That's right. There is no general solution. One can only look
for common patterns and do those. For example,
#define X 15
is a common pattern and can be reliably rewritten as:
enum X = 15;
If I understand it correctly, dpp doesn't do that.
Instead, it runs the pre-processor on the source code, just
like in C, so
// test.dpp
#define X 15
int foo() { return X; }
becomes
// test.d
int foo() { return 15; }
The upside of this approach: all macros just work, unless they
use C (not C pre-processor, C proper) features that dpp can't
handle. `sizeof(...)` is a special case that is handled in
dpp.cursor.macro.translateToD and more could be added.
The downside: macros can't be directly used outside .dpp files.
Yes, I assumed it actually "expands" the macros, whereas it
actually runs
the preprocessor on dpp files:
https://github.com/atilaneves/dpp/issues/30
I can see it perfectly matches the Atila's usecase, and I'm
curious
what are the other usecases for dpp?

I think we have a misunderstanding here. According to that,

Quote from the article:

Meaning that if you declare your `title` member `const char[]
title`, you can't change it in the postblit, but you could set it
in the constructor.
```
import std.array;
import std.stdio;
import std.algorithm;
struct placeAtWorldMap
{ const char[] title;
int[2] coordsMicroDeg;
this(char[] name)
{
this.title = name.idup; // you can assign const
members here
}
this(char[] name, int[2] coords)
{
this.title = name;
this.coordsMicroDeg = coords;
}
this(this)
{// title = title.dup;// doesn't work anymore
}
}
void main()
{ char[] title = "London bridge".dup;
const place = placeAtWorldMap(title, [51_508_038, -87_693]);
const newPlace = placeAtWorldMap("Big Ben".dup);
const samePlace = place;
"falling down ".copy(title);
place.title.writeln; // falling down
samePlace.title.writeln; // London bridge
newPlace.title.writeln; // Big Ben
}
```

Don't remember the exact stops, but I just used google maps to tell me the info. I recommend before you arrive, to go into google maps on your mobile device, and store the Berlin map as an offline area, especially if you do not have coverage. Also, you can pre-plan your trip if you know when your plane will arrive and figure out what the bus/train schedule is. For those not used to the transportation system there, you buy your ticket, and then validate it. If you don't validate your ticket, it doesn't count. I was thrown off that nobody really ever checked my tickets, but I guess you get into trouble if you don't have a validated ticket. 60EUR trouble ;-) Last years thread: Directions to Ibis Hotel in Berlin from Tegel Airport http://forum.dlang.org/thread/nfi108$2b02$1...@digitalmars.com

Maybe someone could post a description of how to get there from the airport. I remember last year there was a detailed description with pictures etc. And beware of Berlin taxi drivers, you might get fleeced. Make sure they have a taxometer and that the taxi license is on display. If in doubt, get out! Yeah, I believe the pictures are still on the last year's topic. Nothing major has changed regarding transport. As far as Taxi goes, see the TXL airport plan here: http://www.berlin-airport.de/de/_dokumente/reisende/lageplaene-sxf-txl/2016-12-27-txl-terminals-de-en.pdf There are two Taxi stations, on the southeast of terminal A, and just in front of terminal C. Usually there's a lot of Taxis there, and in my experience they are all legal. Anywhere else on the airport, you can bet they are dodgy (see http://www.bz-berlin.de/artikel-archiv/die-gierigen-taxifahrer-vom-flughafen-tegel) This all stands for airport Tegel, I have no experiences with Schönefeld.

Is there a way to call invariant() of a class/struct directly? That would obviate the need for a particular predicate (copy the class state, run the setter, check if invariants are satisfied and restore previous state if they aren't). You can call invariant directly with `assert(this);` IIRC.
