[MLton-devel] Basis2002: IO

[Henry Cejtin]

Does the imperative level have something that lets you un-get characters.  Once
you have that you can do pretty much everything, but without it you are kind of
stuck.  (You can handle things as long as only one piece of code is doing the
reading, but otherwise you are pimped even inputing things like integers
without at least one character of look-ahead or un-getting.)
