It would be handy if it was documented how to supply a trust bundle from the host for registries with a private/self-hosted certificate known to the host

Familiarizing myself more with NBench. Started with the readme. Happened to notice:

Low priority / not a big deal, but figured you'd want to have it on your radar.

If I familiarize myself fast enough, I'll submit a PR to finish the sentence. ;)

In tutorial http://www.arclanguage.org/tut.txt, there is a function tostring that is like do except any output generated during the evaluation of its body is sent to a string, which is returned as the value of the whole expression. For example, the expression

(tostring                  
       (prn "domesday")
       (prn "book"))

should evaluate to string "domesday\nbook\n"

Similar to the current ones available for Mac OS I would like to provide a similar installation and run experience on Linux.
