   Hi,   
      
   Dogelog Player is a 100% Prolog written Prolog   
   system for the JavaScript, Python and Java platform.   
    From its inception we let most of the higher order   
   logic programming rest in limbo. Only recently we   
   added call/n and maplist/n, foldl/n, etc..   
      
   The upcoming release will see the introduction of   
   arrow functions via (=>)/2 and filter/3, etc..   
   JavaScript programmers might be familiar with the   
   concept, only our arrow functions are boolean   
   arrow functions driven by the outcome of a goal.   
      
   Diverting from library(yall) of Logtalk provenance,   
   the syntax and semantic of our arrow functions matches   
   that of JavaScript. To speed up loop processing we have   
   already a runtime preprocessing in place. The future   
   might bring refinements, such as ahead of time   
      
   compilation into Albufeira anonymous predicates.   
      
   Bye
