Comments on: Templates http://kosmaczewski.net/2008/03/13/templates/ sin incertidumbre no hay novedad, sin novedad posible no hay más que repetición y, por lo tanto, negación del otro como un ser libre: el ser libre es un ser incierto.

I think somebody somewhere wrote a "Towers of Hanoi" solver in template expressions... It just seems to me it's one of the slower turing machines around ;) It is indeed – template expressions are turing complete, so you can really do whatever you want at compile time.

Indeed I have witnessed (and suffered) those longer compile times, but what I find fascinating is the kind of constructions that you can build with templates. In terms of expresiveness, I think it's huge. Hi Robert, thanks for your comments!

Namely, insanely long compile times once you start relying on these features. To be fair, that's probably mostly attributable to the fact that C++ really wants to be backwards compatible to 1970's style C - include file madness, undecidable parsing, lots of fun....

The big classic is the singleton: template <class C> class Singleton { private: static C instance; public: … } class Toto: public Singleton<Toto> {…} How cool is that? I can even pass child classes as a template parameter of a class. The big classic is the singleton:

template <class C>
class Singleton {
private:
static C instance;
public:
…
}

class Toto: public Singleton<Toto> {…}

How cool is that?
