[Masinter.pa: synonym streams..]

[Jonathan A Rees <JAR@AI.AI.MIT.EDU>]

How about a similar rule for Scheme?  With the obvious extension to ports created by
with-input-file, etc.

I propose the following rule: "It is an error to attempt to close a
stream that wasn't created with open."

With this rule, it would follow that, since synonym, broadcast and
two-way streams are not created with open,  it is an error to perform
"close" on them.
