### lab 48 - symbol

NAME lab 48 - symbol NOTES I'm clearing out the backlog and found this lab's code, which is really a continuation of earlier labs on the lispy-shell (26, 27, 28). I felt that where I was going with lab 28 wasn't working out, or was just going to end up looking like scsh (if I was lucky, and as smart as Olin Shivers). This attempt is more a mathematica-like-shell, and for a while was looking better, in that it fit in better with the existing sh, but now I've decided against it too. I'm posting it here just to record what I've done. I'll try and explain at the end why I don't like this approach anymore. In Mathematica everthing is an expression of the form f[x,y] which translates quite easily into the shell expression f x y Because of Inferno sh's command blocks, we can directly support the nesting in expressions: % Head {f x y} f % Head {f;x;y} List # a sequence of commands {f;x;y} is # represented as {List f x y} in "FullForm" And
