This isn't a request for a feature, merely a thought experiment. We're still in the phase where it's more important to ensure that existing features work properly than add new ones.
How difficult would it be to include a mechanism within the REPL to select either documentation or an example, (possibly from the test suite), for a particular command? Selection might be by some control key combination, cursor positioning, or an alternative to "enter" at the end of the line. The purpose would be to speed development, by enabling an inexperienced developer to look up details while testing. Syntax errors generate messages which attempt to provide help; could this provide the basis for a "help" mechanism? Would this be useful? Opinions?
