I find the remarks a bit discouraging. It is not a bad exercise. It is quite creative as well. I had a look at nymph_compiler.c. Without using a lexer/parser generator, it is a bit hard to guarantee much about what it will be doing, or even to produce BNF specifications. But then again, I think they also abandoned bison for gcc, and started hand-coding the parser. Maybe the bison approach is also naive in its own way:
"A hand-written recursive-descent C++ parser has replaced the YACC-derived C++ parser from previous GCC releases."
"GCC switched to hand-written parsing because error messages are more meaningful when using recursive descent techniques. Also, C++ is becoming such a (syntactically) complex language to parse that using parser generators is not worthwhile for it."
It is strange, because the more complex the language, the more I would expect that they would move to lexer/parser generator tools, while it seems to be exactly the other way around.
Well, bitcoin makes people who think that they are smart, realize that they are way less smart than they thought they were. The author understands that he could impossibly understand the underlying mechanics of bitcoin. Hence, he came to realize that there must be other people, who are substantially smarter than he is.
Half of my work is to develop and maintain a devops console for the application. I could indeed have spent that time building new features, but we are not necessarily interested in what else we could add, but rather in what else we could leave out. In der Beschränkung zeigt sich erst der Meister.
