Using "regexex" for doing what is terrible? Using regexes for a lexer is quite common, and if you read his code, that's what he is doing, and then feeding the tokens to the parser.

If you are talking about ASCII(7 bit ascii and not extended ascii), then it can't happen - the encoding is same for 0-127.

Side effects can be checked in `@leave(check_side_effects)`. I plan to add something to check results.

The waters are murkier here. Apart from checks, you also have @transform_args(a=lambda x: x*x) def foo(a): pass This isn't validation and can't be turned off. The idea behind the project was the function should concentr

Won't that defeat the whole point? Contract based programming means your function assumes certain properties and acts accordingly. If you turn off the contract enforcers, your function will still be acting under the assumptions that the in

I liked contracts in Racket, so ported some of it to Python. These checks can very well be done inside the called function but decorators enable a more declarative style.

A bit OT and not sure if you will see this. Seeing that you are the guy(or onof the guys) behind redis which is written in C, do you have any recommendations for generic data structures and operations on them? I personally have a trivial ve

If you are developing, `gcc -g` while compiling(or CFLAGS += g), and loading the core with gdb does give a very good idea of what went wrong.

No, I was thinking binary 19. Does C say the implementation is going to be 1s complements, 2s complements or whatever? Is there anything that says, for example, it can't be BCD?

May be a good idea to mention some of them. `valgrind` and `lint` comes to mind. On second thoughts, `lint` can be dropped; compiler warnings are good enough for a beginner(in fact, good enough for experienced programmers; subjective).

C is difficult, yes. Dangerous - I don't know in what sense. I manage to get more exceptions in my Python, Ruby code, owing to undefined variables or incorrect types, than I get segfaults in C. The main issue with C is it takes some time be

Sometimes due to language discrepancies, skills don't transfer and there is no easy "feel free to skip to chapter x". For example, a conversant Python programmer's idea of string, and strings in C are 2 different things. A conversant C prog

I don't think Khan claimed about teaching expert level material. `Superficiality` is a strong word. Zed Shaw's LPTHW is for beginners, but not superficial. Similarly, most of Khan's lectures target a particular audience. Some of his lecture
