other misc. cleanup
 2009-07-20 04:57:17 +00:00
JeffBezanson 642d1e1bd4 rewriting some primitives to take advantage of the full language; they 
do not need to be written in terms of the base language any more

  compiler where it belongs. macroexpand now only handles syntax.

  lists not preserved

JeffBezanson 43e8d1fbf0 adding the ability to heap-allocate extentions to the value stack,

reorganizing evaluator so the same code is used for evaluating
and pushing arguments for both builtin functions and lambdas.
for now this is slower, but it was done in preparation for
Things To Come.

adding list-head

implementing the calling convention for long argument lists in
bytecode compiler. arguments are broken down into a nest of
list and nconc calls.
