5.6.4 Inspect

INSPECT is an interactive version of DESCRIBE. The nature of the interaction is implementation-dependent, but the purpose of INSPECT is to make it easy to wander through a data structure, examining and modifying parts of it.

INSPECT is like DESCRIBE, but instead of printing the information it presents the information in some kind of interactive display; typically either a command loop in the current listener or a new window with its own user interface.

Implementations are encouraged to respond to the typing of ‘?’ or a “help key” by providing help, including a list of commands.
