yes, the latest proposal I made in the note I circulated on sunday night
(which subsumes all my other proposals, including the early ones that
still are in chapter 4) was to _add_ a content dictionary calculus3 with
term+variable versions of the symbols and _keeping_ the calculus1 CD.
The pragmatic-to-strict translation would then pick the appropriate
symbol depending on the content, just as in s_dist and s_data.
