@item Description
The core standard for the Scheme language.
@item URL
@url{@value{R7RS_URL}}
@item Support
Fully supported, with exceptions:
@itemize @bullet
@item
Multiple values aren't supported correctly.  Instead @code{values}
returns a special record containing the values, and
@code{call-with-values} takes that record apart and passes the values
to the receiver.  For many uses of multiple values this is adequate.
