I would consider exposing an optional second argument to `read', for
read options.  Probably Ludo and Mark disagree?  But I think for Scheme
the cyclomatic complexity is not that bad, as we are replacing globals
with a parameter that we pass around anyway.  I would expose
(current-reader-options) as a parameter, and have it be the default
value.  Updating the current read options would update this parameter
somehow.  Could we consider a read-enable FOO as updating the binding in
the current dynamic state only?

Maybe I'm totally wrong here :)
