A GUI-based 64bit 'hello world' application with LispWorks on the Mac is around 13MB in disk size. A mocl application might start around 1 MB. But that's an unusual whole-lisp-program-to-c compiler.

Original Lisp vendors (Lucid, Symbolics, TI, LMI, Xerox, Franz, Harlequin, Goldhill, ...) and other companies selling CL (HP, DEC, IBM, Apple, SUN, Tektronix, ...) did market it, but that ended in the mid 90s with many of them exiting the b

One writes in a hierarchical data structure: s-expressions. Since Lisp has built-in macro expressions, on top of s-expressions, one can represent code independent from 'ASTs' and make it executable: For example the LOOP macro intr

One does not write 'directly in AST' in Lisp. Lisp is written in nested lists of prefix expressions. Instead of foo(bar(1,2)); one writes (foo (bar 1 2)) Instead of function foo(bar) { bar.baz = "hello&q
