[slimpl] The REPL has landed

[Larry Clapp]

Hi, all,

I still have some test cases to write, but I got a REPL talking to a
real Lisp:

  use slimpl;

  [...]

  # Set up a slimpl object.
  my $s = slimpl->new();
  $s->connect( "localhost", 4005 );
  $s->select_connection();

  while (1) {
    # print a prompt
    print "> ";

    # read a 1-line s-expr
    my $expr = <>; chomp $expr;

    # quit?
    last if $expr eq 'q';

    # eval the expr
    my $val = $s->eval( [ symbol( "swank:interactive-eval" ), $expr ] );

    # print the result
    print "result is $val\n";
  }

Short transcript:

  > (+ 1 10)
  result is => 11 (#xB, #o13, #b1011)
  > q

Time permitting, I hope to release some code & documentation this
weekend.
