None of these proposals are going to address the main problem: most Emacs modes depend on a lot of regular expressions for syntax highlighting and many other things. Regular expressions are slow; it is a computational complexity problem. Th

It is worse than that. First-class continuations add a small overhead for stack operations, and they always have more memory overhead than callbacks/async transformation into callbacks. But the comment I was replying was about Go, not

I have ordered from Thriftbooks dozens of times. The only two things that happened was one package theft (obviously not their fault, but they re-sent the books for free, no questions asked), and one extra shipment of books I had not ordered

Keyboards generate scan codes, not characters. The character translation is all done in software. How do you think input language selection works?

Smalltalk (among other languages of the 1960s and 1970s) had a left arrow symbol as the assignment operator. 95 was ← instead of _ in ASCII pre-1967. Also, anyone pretending to be a competent computer programmer while whining about being un

BWB is also the only online bookseller that seems incapable of delivering their orders consistently. I have given up trying to order from them.

I don't understand, what is there to set up? With the Emacs mode I gave as an example, you just open an XML file and everything is there. Any decent text editor will have XML support.

Not only that, the "Common" in Common Lisp is a reference to a standardization of several existing dialects, so a lot of Lisp code from the 1960s and the 1970s will run without any modifications.

SGML being replaced by XML being replaced by JSON is great proof that the idea of progress in tech is at best a myth and at worst a lie.
