Back in 2014, @Egon pointed out a problem in the Standard Library wherein if you interrupt incomplete input with a metaverb, the game will forget what you were doing. The bug is written up here:https://gitlab.com/DavidGriffith/inform6lib/-/issues/64. For instance:
>take What do you want to take? >trace [Trace on.] >gold key That's not a verb I recognise.
All this time, I’ve been unable to figure out how to make the Library backtrack after processing a metaverb. Could I get some fresh eyes to look at this?
