§21.7. Lists of values matching a description
The useful "list of ..." syntax can also be used to produce lists of the values matching a description, too. Thus:
let L be the list of non-recurring scenes;
let C be the list of colours;
There is little to say here except for the usual warning that some kinds of value have a range which is too large to make this possible. For instance, Inform could not sensibly represent:
It would just be too large to hold. In general, if we can repeat through, or find the number of, values matching a description, then we can also use "list of" to bring them all together. See the chart of kinds of value in the Kinds index for a project for which kinds of value allow this.
