[R6RS] Core/library questions

[Anton van Straaten]

If we have time on the call today, I'd like to briefly get editor 
reactions to the following questions (responses in email are fine too, 
of course):

* Should the eof-object constructor and eof-object? predicate be in the 
core, or one of the I/O libraries?

* Should predicates such as exact?, inexact?, flonum? and fixnum? be 
moved to the core, out of libraries such as arithmetic-exact etc.?

* Should 'when', 'unless', and 'case-lambda' get their own library (as 
we originally voted), and if so, does anything else belong in the same 
library (such as 'do')?  Note that this library could be included as 
part of either the 'r6rs' or 'r6rs-big' compound libraries, so can still 
be obtained without having to specify a separate library when importing.

* Should generic arithmetic have its own library (as currently listed in 
the core/library proposal), or should it be in the core?
