Let us keep the adverbial writing challenges/exercises open (non-tacit
solutions are also welcome).  Why not?  ;)


Mapping nouns to proverbs...


Exercise 9.0

Produce an adverb  boolean  such that it maps the  b.  codes to their
corresponding proverbs; thus,

   'and or rotate shift signedshift'=.  17 23 32 33 34 boolean

   NB. Alternatively,  (and`or`rotate`shift`signedshift)=. 17 23 32 33 34
boolean if the names
   NB. and, or, rotate, shift  and  signedshift  are undefined or
predefined as verbs

   NB. 64-bit...
   assert 48 80187 -: 12345 (and , or) 67890
   assert 2468 -:1 rotate 1234
   assert 576460752303423102 _386 -: _5 (shift , signedshift) _12345


Exercise 9.1

Produce an adverb  circle  such that it maps the  o.  codes to their
corresponding proverbs; thus,

   'sin cos tan'=. 1 2 3 circle
      NB. Alternatively,  (sin`cos`tan)=. 1 2 3 circle  if
      NB. sin, cos and tan are undefined or predefined as verbs

   (sin`cos`tan)/. o. 3 %~ 0.25 0.5 0.75
0.258819
0.866025
       1

   'asin acos atan'=. (-1 2 3) circle

   assert (,. -: (asin`acos`atan/.) @: (sin`cos`tan/.)) o. 3 %~ 0.25 0.5
0.75

As far as I know, there is no way to solve these exercises explicitly;
however, one could use instead the related forms  '`sin cos tan'=.  etc.  The
tacit solutions, after running the Tacit Toolkit [0], are straightforward:

9.0 Solution

   bdot=. b.
   bdot=. Ver'bdot'        NB. Verbing the adverb b.
   Map=. (<@:)("_1)f.      NB. Boxing items and fixing (adv)

   boolean=. bdot Map adv  NB. (fixed)

A direct simple alternative is to use the higher-order verb produced by
 bdot Map ,

   'and or rotate shift signedshift'=. bdot Map 17 23 32 33 34

Likewise,

9.1 Solution

   ampercircle=. &o.
   ampercircle=. Ver'ampercircle' NB. Verbing the adverb &o.

   circle=. ampercircle Map adv   NB. (fixed)

Again, a higher-order verb is a direct simple alternative, for example,

   'sinh cosh tanh asinh acosh atanh'=. ampercircle Map (, -) 5 6 7

   assert (,. -: (asinh`acosh`atanh/.) @: (sinh`cosh`tanh/.)) o. 3 %~ 0.25
0.5 0.75
