The idea that the "Lisp programmers" are somehow adverse to mathematics is historically untenable. Macsyma was written in Lisp. And Macsyma was one of - if not THE most important application for the Symbolic Lisp machines (the ancestor of all later Lisp machines). Many later systems (Maple, Mathematica, ...) were written by people who would consider themselves belonging to the Lisp crowd. For example all of those systems had automatic memory management with garbage collection, most had closures/lambdas, etc.
