The transform would have to be made at a low enough level where purity no 
longer matters, perhaps in codegen. (Until we get a GC that penalises mutation.)

I wouldn't mind adding `list*` at all. (It would eventually compile to list + 
nconc, of course.)

We could make backquote emit `list*` and avoid stack overflow problems of the 
sort that was mentioned earlier (or maybe it was something else).
