Datalog - A lightweight deductive database system with Racket
integration is available in the `datalog' package and with `#lang

web-server/formlets adds a 'formlet*' form that allows dynamic formlet

The Advanced Student Language now supports hash-table primitives,
`define-datatype' for defining sets of related structs, and `match'
for pattern matching.
