some refactoring of string-to-number parsers

b586d2e21a
some asserion violations in the reader are converted to &lexicals so
...
that the repl displays them properly. E.g.,
(read (open-string-input-port "#!r6rs |foo|")) shows an &assertion,
but typing #!r6rs |foo| at the repl causes the repl to reset without
a message.
2009-07-30 21:46:11 +03:00

Ikarus now supports PLT's Scribble syntax!
...
- The only thing unsupported is the transposition of punctuations,
e.g., @`foo{bar} => `@foo{bar}.
