Was looking for lists of underlying lisp hardware DS / (ebnf) terminal node (aka lisp 'cons' form ) for a given lisp implimentation. ** x = 1 aka s-expression cons on symbolics machine would map to a linear array / stack. ** x < log(1) Are there modern non-stack based follow-ups? aka revised symbolics approach, not necessarily in direction symbolics went, perhaps ranslations to asci / neural net / 'dna' organizational hardware? *** x > log(1) Guess lisp using math to not get in the way of language designer/programer to allow language to conform to subject at hand doesn't make for similar categorical discussion as algol family of languages. Lisp lanuage & reasoning for dialect closest 'broad category/taxonomy of dialects' without getting into specific subject domain / 'what lisp get's compiled to'. aka: ** Lisp generational groupings per ebnf terminal node: 1st generation, use of "point" forms : encoding schemes / Lisp macro -- data 'point' 2nd generation, use of functional forms : scheme -- line segment / group set 3rd generation, use of topological forms : Haskel / ARC -- function
