This refuses to work on inexact numbers and procedures.  Use it in
`check-expect' & friends.

8032705cf9 The call to display-results depends on the value of the current-namespace 
parameter. Specifically, it is expected to be a namespace that has the GUI
bindings available. Unfortunately, during the dynamic extent of the
uncaught-exception-handler when a syntax error is raised, this may not be
the case because you get a phase 1 namespace, not a phase 0 one.

So, move the call to display-results to the code that runs the student language
programs and out of the uncaught exception handler.

6ac33a62be set `read-accept-lang' to #t by default, plus related adjustments 
including adding some uses of `with-module-read-parameterization'
 so that `read-accept-lang' is set right anyway; still, so many
 many places just set `read-accept-reader' to #t that making
 `read-accept-lang' #f by default looks like too big of an
 incompatibility

9b1188c77a Re-instate Robby's hack to display test results off REPL errors. 
... and generalize it so there's an action before (clearing the old
tests out) in addition to after (displaying the test results).

Also, do for DMdA as for HtDP.

2189957b6f Change the errortrace protocol for `initialize-test-coverage-point' and 
`test-covered' to use just the expression -- looks like there's no
reason to use an additional key.

Also, change its uses to map each syntax to an mcons where its mcar is
used to track coverage.  This is done everywhere, since it turns out to
be much faster to insert a `set-mcar!' with a 3d mpair, rather than a
call to a thunk.

Note that it still uses mpairs as a hack.  It "works" in the same way
that this simplified example does:

  (define-syntax m
    (let ([b (mcons 0 0)])
      (lambda (stx)
        (with-syntax ([b b])
          #'(case-lambda [() (mcar b)]
                         [(x) (set-mcar! b x)])))))

I think that it's fragile, and likely to stop working at some point, but
I don't see anything better for now.

5e04a5c6d9 When opening a new window where the language is one of the htdp languages (via the 
language dialog, not the #lang htdp/* variants), teachpacks are put into the
initial REPL (instead of just having the language primitives).
