Pounce needs a map combinator, working on it here...

map.alpha.pounce

// a definition of 'map'
{
 local-words:{
  map-repeat: [dup 0 > [1 - swap dup dip2 swap map-repeat] [drop drop drop r get [drop] dip] if-else ] 
  map-package: [{} swap f set swap o set [] r set]
 }
 fn:[map-package
  [o get dup str-length 0 > [pop [f get] dip2 2 bubble-up apply [o set] dip [r get ] dip prepend r set] if] 
  [dup [apply] dip] [o get str-length] dip2 2 bubble-up map-repeat
 ]
} [map] define

// a quick test of 'map' negate the only the even numbers...
[dup 2 % 0 ==] [is-even] def
