Metaprogramming generally involves complicated code like that. The choice is really simple: either the language allows it, and then some features can be implemented as a library (and we see the immediate benefit of that in this case, where the library can be rewritten to optimize it for some specific use-case), or else the language doesn't, and then those features have to be implemented as language constructs, or are omitted entirely. |
