like textual-read-eval-print-loop
There is still a difference, however, because drracket's REPL has a
notion of multiple expressions that are submitted simultaneously that
textual-read-eval-print-loop doesn't. For example, if you type this at
the prompt:
(car) (+ 1 2)
then textual-read-eval-print-loop will print out the error and then 3,
but drracket will print only the error (ditto if (car) were replaced
by a continuation abort).
This difference is, IMO, a good thing, since it lets you use a single
interaction to do multiple things, but stops as soon as there is an
error. (It is also how drracket has behaved for a long time.)
closes PR 12790
(since the repl test suite tests the pretty big language's repl and since there was a test case
there that would have discovered a bug that we only found in the hours before the release but had
been lurking for a few days)
Removed "info.rkt", since all entries were unused; switched ".ss" to
".rkt" in both real code and tested code (except for the teachpack
tests); modernized some tests to use symbolic requires (which would also
make it easier to deal with).
