The accumulate phrase:

   - must follow "from"
   - may contain inline code (init, action, result)
   - may have a single accumulate function call

The accumulate CE

   - can be used in combination with a pattern, "not", "exists", "eval" and
   "forall".
   - may *not *contain inline code
   - may have more than one accumulate function call

So it seems that "accumulate" is going to stay, at least for the phrase. If
"for" is then used for the extended accumulate CE, there'll be "for" and
"forall".
