2.33.2 Issues

Procedure names have been chosen to be consistent with R6RS, even though in some cases such as list-ref and list-tail the choice seems poor since they include the prefix list- even though they do not operate on lists, but chains of pairs, i.e. lists and improper lists, and arbitrary objects, respectively. Although the names have remained the same, the descriptions have been corrected (e.g. using pair or obj instead of list for parameter names). Should the names be changed as well?

To what extent should standard Scheme procedures and syntax that consume or construct lists be included in this proposal? For example, should all of the (rnrs base) library that deals with lists be included? By my count this would mean adding: lambda, apply, vector->list, list->vector, string->list, and list->string. I am inclined to add these. Should all of the (rnrs lists) library be included? These procedures are easily defined in terms of what’s given here, and no performance advantage is gained by implementing them “under the hood” using the data structures in the reference implementation. I am inclined not to include them.

Should a car+cdr procedure be added?

Should the current syntax and procedures sub–libraries be included?
