% The following list gives property-list indicators in roughly the
% order of priority across the whole range of REDUCE test files provided
% with REDUCE 3.6. For each test the number of successful and unsuccessful
% property-list accesses was counted. (S and F). The score S+2*F was used
% to allow for failing accesses needing to scan all the list, while
% successful ones only go on average half way. For each test scores for each
% particular indicator were expressed as percentages. Tables of all these
% percentages were put together and sorted - the list that follows is what
% emerged when only the highest-placed mention of a tag was kept. The effect
% should be that the most heavily used tags in each test come in this list.
% This list can be longer than the number of fast-get tags I support and only
% the relevant number of items on it will be used.
