You would normally read the whole expression and then evaluate it.  I've
never seen a lisp that evaluates concurrently with reading, except
through things like read macros.  Try to relax your Forth reflex of
feeling pain at the thought of temporarily allocating a half dozen extra
cons nodes.  They get gc'd, and also, Lisp historically always ran on
relatively large machines compared to typical Forth platforms.  

Lisp's heyday was more or less in the same era as Forth's (1980s) but
most interesting Lisp projects at that time ran on 32- or 36-bit
machines with a megabyte or more of memory, while Forth typically ran on
8- or 16-bit machines with 64k or less.  Lisp had the reputation of
being a horrible memory hog, but these days of course, 1MB is nothing.

Anyway, it is ok in Lisp to read in an entire large function as an
S-expression before trying to process it.
