I just added an example to Artifacts with one way of using the qresults-list package to create a table and manipulate it with a right-click menu. I added quite a few comments which, I hope, will help people wanting to figure out how to use the qresults-list package. This package has been

Re: [racket-users] Is it possible to simulate FEXPRs in Racket?
