There is a naming tradition in the Lisp world, which Racket devs apparently have chosen over searchability.

Qualities or activities that have negative connotations. Guile. Gauche. Larceny. Racket.

I think it started with theorem provers - Planner, Conniver. Then Scheme[r].

A funny thing was, when the rename to Racket was still fairly new, someone started looking into adopters in the finance space.
