Robby Findler (Northwestern University, USA), gives the first talk in the first panel, Domain-Specific Languages, on the 3rd day of the ICFP conference.

Co-written by Vincent St-Amour, Daniel Feltey, Spencer P. Florence, Shu-Hung You, Northwestern University.

Racket is the ultimate abstraction-abstraction, a platform for quickly and easily building new ultimate abstractions. This pearl demonstrates Racket's power by taking a leisurely walk through the implementation of a DSL for Lindenmayer systems, the computational model par excellence of theoretical botany.
