Hi Erling, You are right, the adverb (At) produces tacit sentences but it is really an implementation of Dan's pipeline proposal using strand notation via a Curried adverb (aka, recurrent adverb and multiple adverb). However, I have written (tacitly) a tacit Curried adverb (xi) which, using a lam

You have my proposal right.  It is like d-fns.  There is no new added functionality - in fact there can't be, because every (. ). function is converted to an explicit definition. The benefit is ease of creating explicit entities, even if they are anonymous, multiline, or nested within other en
