the two language problem performant productive (lisp, python, ruby, matlab) (asm, fortran, c, c++) either write code efficiently … or write efficient code
typical workaround? use two languages (prototype + production) ergo the two language problem
“l ooks like python, feels like lisp, runs like c “
…l ooks like python… # python # julia def sum(a): function sum(a) s = 0.0 s = 0.0 for x in a: for x in a s += x s += x return s end return s end
… feels like lisp… homoiconic dynamic parametric multiple dispatch highly polymorphic …
… runs like c … # python # julia def sum(a): function sum(a) s = 0.0 s = 0.0 for x in a: for x in a s += x s += x return s end return s end
“l ooks like python, feels like lisp, runs like c “
