Thanks to R. Henry for keeping us up to date on the proposed standard.

A question about implementation:

 I am trying to figure out how to implement procedures which don't
 consume input, but may have to read far ahead, when the input is for
 example a terminal or a pipeline.  Good examples of what I mean are
 Int.CanRead and Int.Value.  Suppose the input is from a terminal, and
 the person sitting at the terminal types an endless stream of spaces.
 Should CanRead return FALSE after filling a buffer?  Should Value halt
 with an error after filling a buffer?  I can't think of anything else
 which would be reasonable, and I'm wondering what the proposers have in
 mind here.
