I explicitly made “,build” hide that difference; I thought one would just want “,build” to do the right thing and display the resulting store item regardless of that kind of detail. Conversely, “,lower” is for die-hard hackers and it doesn’t hide any subtlety. >> +(define* (evaluate/print-with-store mvalue #:key build?) >> + "Run monadic value MVALUE in the store monad and print its value." > > I do not know if it makes sense to have a list of monadic values, > allowing something like: > > ,build hello coreutils I don’t think the REPL can support this syntax, but we could add support for: ,build (list hello coreutils) Thanks for your feedback!
