Put some vertical space between internal definitions and the procedure bodies. I hope the indentation is still visibly apparent....

No. No Schemer worth a salt would tag a Scheme post as [lisp].

I ended up creating a truthy=? that uses not. It's like XNOR with a more readable name. :-D

Add a `truthy=?` operator that removes the need for the predicate to return a boolean. Thanks to Martin Neal for the idea.

@MartinNeal Mostly because, if I'm going there, I may as well define an XNOR operation. Which I'm still considering doing. :-) But actually, I think I can adapt your idea to use not instead, so that instead of using (and foo #t), I'm just using (not foo) (and swapping the branches, of course). Edit coming up.

Since you bother to call out the gotcha with lt?, why not fix the code like so: (eq? (and (lt? (car r) (car l)) #t) flip)

Young | @RobertHarvey I'm looking for general critique of style, as well as ways to make the code even more performant (algorithmically speaking, not so much micro-optimisation-wise). I actually do have a more performant version of this code, which I'll post as an answer. Soon. :-) | |
