There is also "The Fine Article". FWIW, all these things date back to the ancient Usenet "RTFM" (where M = manual) which would undermine an expansion of "featured" in my view (since manuals are not "featur

Indeed. It is pretty easy to just write some Cython routine against the data pointer & range lifted out of some NumPy array and then still let Python do all the memory management for you. I think Cython is great for just speeding up pr

This is indeed an ancient problem. I loved the 1992 Lisp FAQ comment by jjwiseman. :-) Nim handles this with `closureScope` and `capture` ( https://nim-lang.org/docs/system.html#closureScope.t,untyped ). It's deb

Yes. The kind of type modeling this is doing is not very physics-unit-minded at all (where any multiplicative operation potentially creates a new type). Rather, it is trying to prevent non-additive (add/subtract/compare) operati

I think there is a reconciliation. If you read the other article popular today ( https://news.ycombinator.com/item?id=37493955 ), it focuses on scale invariance as the driving principle and gives an example of units for Four

This has maybe been said before and given how abstract both this and the recently discussed ( https://news.ycombinator.com/item?id=37493955 ) article are, it feels weird to say they are insufficiently abstract, BUT.. if you c

I agree this particular C# being >180x slower may not matter much for one-off commands keyed-in by and watched by humans, but that may not be all that matters. E.g., some people might `find . -print | xargs -n1 cmd`. Almost everythin

This comment is misleading &| misinformed. Sum types are built-in [1] for formal parameters. `nil` is only for `ref|ptr` types. In much code you can just use stack allocated value types and there is neither GC concern nor nil concern,

No problem. It might also bear mentioning that if one is willing to learn more specialized tools, even less key-downing is possible, such as (using https://github.com/c-blake/bu/blob/main/doc/cols.m

Often whole program generation in a prog.lang (& ecosystem!) that you already know can substitute for a new prog.lang. Python even has eval . You may be interested in: https://github.com/c-blake/bu/blob&#x

This kind of thing should probably be generalized so that any new parameter can be seamlessly woven into your `ls-like` reports. https://github.com/c-blake/lc/blob/master/extensions/fe1 does `du` (l

I'd bet you could do a harness like https://news.ycombinator.com/item?id=37292882 mentions but with Python in like an hour and then you could stay in both one syntax and more significantly in one library ecosystem. Wh

You might consider: https://github.com/c-blake/bu/blob/main/doc/cols.md That's in Nim, though that may not be much a barrier. (There may also be other tools in bu/ of interest.)

I agree that "writing/learning a different" (what I meant) is more clear wording than "making a whole new". EDIT: and it is a fair counterpoint that any command with options is, in some sense, also a different lan

Of possible interest - instead of making a whole new programming language like awk, you can also just systematize generating code for an existing one with a command-line harness. This can even stay terse & keep a fairly fast edit-test t
