Why HN links it

HN readers link this Common Lisp writeup for its type hierarchy diagram. Commenters use the diagram to ask how built-in types like base-char and character relate, and one posts a fuller type tree.

Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

So is character a class too? does base-char encapsulate a character or something like it? Before anyone comment, please keep in mind that this comment doe…
