That command uses `#lang racket` which means it loads an awful lot of modules. Try an example with `racket/base` instead. $ time racket ~/tmp/bd.rkt hello Times: 0.12s user 0.04s system 94% cpu 0.176 total

The "blog" consists of detailed examples of how to draw 2d figures using Metapict. Metapict is what I imagine Metapost and Tikz would have looked like, if they were written in Racket.

Yes, a different story. The idea is that attaching information on "stack frames" might be useful for other things than stack traces. The reference linked to is precise, but do not show the utility. The rationale here gives a bette

I am curious, did you look at "continuation marks" too?
