Abstract

Interactive REPL-driven systems (that most Schemes are) need a way to get detailed information on a given piece of data. Inspectors, as these are conventionally called. This SRFI defines a basic protocol for inspectors, consisting of two procedures: inspect-properties and inspect-describe. Some suggestions for standard and popular types’ inspection are also provided.
