Ator posted:the problem with lisp is all the stupid parentheses!! as a junior junior coding learner (3rd grade), once I learn why there were parens around expressions, it wasn't hard to understand. getting that explanation, and why an expression was different from a special form was different from a macro and why there are at least six different kinds of equality *was* hard to understand.

Nude posted:The only time I've seen lisp talked about in a practical way is in emacs. Hell, I'll be willing to bet that anyone who is serious about lisp also passionately uses emacs. in my journey to become a scootypuff jr. computer toucher, i worked through lisp/scheme tutorials, and it's been very instructive and fun making ~* ELEMENTAL COMPUTATION *~ out of basically nothing. like you can build a couple of crap versions of useful data structures, and inefficient sorting algorithms out of those crap basic elements and putting that together tickled me. is it practical, not because it is the year of our lord carly rae jepsen 2017, and computer touching is about knowing standard libraries and how to glue them together with other things to get the results you want.
