@subsection{Scheme Standard}
The default language is mostly compatible with the
@hyperlink["http://www.schemers.org/Documents/Standards/R5RS/HTML/"]{R5RS} and
@hyperlink["http://scheme-reports.org/"]{R7RS}, with all
differences made by design, not through difficulty of implementation.
The default language is based on the latest draft of
@hyperlink["http://scheme-reports.org/"]{R7RS}, which is mostly a
superset of
@hyperlink["http://www.schemers.org/Documents/Standards/R5RS/HTML/"]{R5RS}.
Some of the more expensive bindings are not included in the interest
of size and quick startup, and some extra low-level utilities are
included for convenience and bootstrapping.
The following procedures are omitted:
To get the exact R7RS language, you can @scheme{(import (scheme base))},
and likewise for the other R7RS libraries.
@itemlist[
@item{@scheme{transcript-on} - in R5RS but not R7RS}
@item{@scheme{transcript-off} - in R5RS but not R7RS}
@item{@scheme{rationalize} - pending the addition of rational numbers}
]
@margin-note{Exact non-integer rationals are planned for a future release.}
Apart from this, the reader defaults case-sensitive, like R6RS and R7RS but
unlike the R5RS. The default configuration includes fixnums, flonums and
bignums but no exact rationals or complex numbers.
The reader defaults to case-sensitive, like R6RS and R7RS but unlike
R5RS. The default configuration includes the full numeric tower:
fixnums, flonums, bignums, exact rationals and complex numbers.
Full continuations are supported, but currently continuations don't
take C code into account. This means that you can call from Scheme to
