That's not entirely true, but it's a valid reason to prefer using musttail. `register` is a hint if you don't specify which register you want to use - however, if you specify the r…

> What practical patterns are enabled by TCO in C? Continuation Passing Style - an important construction for interpreters, but which is also useful for compilers as it's a nice wa…

That may be true, but it may also mean you utilize more memory than you need to. If you aren't shrinking the array when you no longer need previously allocated capacity then you're…

I don't think it's that rare. I've been using the technique for years, and I've seen it done in other work. Bagwell's VList[1] for example uses the equivalent of `bit_ceil` to dete…

If you use a struct with a `void*`, you also need to specify the type on usage, where here it's done with `typeof`.

In C23 this approach is nice, but in older versions of C we end up with awful macros where we need to define the structure before we use it. #define Array(T) struct array_##T #defi…

The reason the struct is avoided here is so the array can be typed to its element type (rather than casting to and from `void*`). With a struct we would need one struct for each el…

The concept of not storing capacity isn't silly. If you need to reserve space then it's not the appropriate structure, but it's otherwise fine. However, using an 2-element array to…

Really? It's been done plenty and I thought was quite common knowledge. Some of the provided functions are basically for this purpose. stdc_bit_ceil(len) gets the smallest power of…

Bitcoin has a variable width encoding (`CompactSize`), but it doesn't prevent overlong encodings - however there are various canonicalization rules in the Bitcoin protocol to requi…

The C charter has a rule of "no invention". Anything needs to be demonstrated and used in practice before being included in the standard. The standard is only meant to codify exist…

Lisps are expression based languages, but not pure. It's easy to mistake it as "like most other languages", but it's not quite the same - everything is an expression and returns a …

Operatives are based on FEXPRS from older lisps - they're basically a function-like form, but where the operands are not implicitly reduce at the time of call. (foo (+ 2 3) (* 3 4)…

There's no "external representation" for environments. In klisp it will just print: [#environment] The environment type is encapsulated, so it doesn't give you very useful debug in…

I use klisp[1] and bronze-age-lisp[2] mostly for testing, as they're the closest to a feature complete implementation of the Kernel Report. I've written a number of less complete i…

I understand the use case, but Scheme macros never felt intuitive to me. I think it may be the quotation more than anything that I dislike - though I also dislike that they're seco…

Operatives do that for me, better than macros. Parent is correct that macros are compile time, which gives them a performance advantage over operatives - but IMO, they're not bette…

In Kernel I would use something like this: true #t false #f null () [...] (& ...) "k" : v (: k v) {...} (@ ...) Where &, :, @ are defined as: ($define! & ($lambda args (cons list a…

When I learned Scheme, I liked the language but strongly disliked macros and quotation. I'd only been using it a short while and when I searched for solutions to a few problems the…

It's potentially useful for computer algebra with complex numbers - we might be able to simplify formulas using non-standard methods, but instead via pattern matching. We might use…

The difference is that 90s games had novelty at the time - many introduced new gameplay ideas. A lot of today's AAA games have converged into a small number of genres like the open…

The subway system in Kyoto (Karasuma line) is operated by the local government. I visited during the busiest time of the year (Gion matsuri), and the trains were not overcrowded, w…
