Not so much macro magic, as not having to dispatch at runtime to the correct sequence constructor. (There is some magic if you use literals though).

Scheme's `do` is implemented using recursion. There's a sample macro for it in 7.3.

DSP chips are a common exception that people bring up. I think some TI made ones have 64 bit chars. Edit: I see TFA mentions them but questions how relevant C++ is in that sort of embedded environment.

No, I mean do. It's basically just a C style for loop except with a return value. Nothing special.

Racket splits up the iteration forms from what to iterate over (sequences[1]). You can compose different sequence constructors together, or make brand new ones, without introducing new syntax. It has limited destructuring - sequences can

If I used Common Lisp more I'd probably have a go at copying Racket's `for` forms[1]; they're really nice because you can usally tell at a glance what they're going to return - `for/list` returns a list for example.

`do` is very straightforward and basic compared to the things that `loop` allows.

by shawn_w 2y ago
And then there's Scheme, where there are no iterative loops; all looping is done with recursion. You can build pretty much everything other languages do with loops on top of that, though.

It's just as easy to have thin wrappers over C/etc. number crunching libraries in Common Lisp as it is Python. And pure CL code is typically faster than pure Python (though pypy might be a different story). There's no technic

I wonder if they were testing with the paid, commercial version or the free evaluation version of LispWorks, which has significant restrictions. Most people playing around with this will be using sbcl though. It's overwhelmingly the mo

I suspect that if you're fluent in the language, understanding an expression written in it comes just as easily and quickly as reading a sentence in a book does to me.

puts() adds a newline at the end. gcc will happily turn printf("%s\n", str) into puts(str), though. I've never tested to see if printf("%s", str) becomes the equivalent fputs(str, stdout)

For SICP, the best option is probably Racket with the sicp language package. I can't recommend MIT Scheme for anything these days; it's just missing too many things that I feel are required for real work in Scheme, and has too man

In my experience, guile these days is often faster than chicken, even compiled (the csi interpreter is dog slow and not suitable for anything but interactive exploration). Chicken is just not a fast implementation. Plus guile comes with a m

It's not based on the Transit. One of the submitted designs was, but it didn't win the contract bid. Edit: looks like it was an early prototype from Oshkosh with very little in common with the final product: https://www

Mostly yes, and it doesn't help that the template heavy API makes it really hard to improve things internally without breaking the ABI. See https://stackoverflow.com/questions/70583395/why-is-stdregex...

Maybe if all you want to do is unconditionally extract certain columns from your data. But even in that case cut doesn't let you use a regular expression as the field delimiter.
