+@settitle The limit procedure
+
+@deffn {library procedure} limit proc x1 x2 k
+@deffnx {library procedure} limit proc x1 x2
+
+@var{Proc} must be a procedure taking a single inexact real argument.
+@var{K} is the number of points on which @var{proc} will be called; it
+defaults to 8.
+
+If @var{x1} is finite, then @var{Proc} must be continuous on the
+half-open interval:
+
+ ( @var{x1} .. @var{x1}+@var{x2} ]
+
+And @var{x2} should be chosen small enough so that @var{proc} is
+expected to be monotonic or constant on arguments between @var{x1} and
+@var{x1} + @var{x2}.
+
+@code{Limit} computes the limit of @var{proc} as its argument
+approaches @var{x1} from @var{x1} + @var{x2}.
+@code{Limit} returns a real number or real infinity or @samp{#f}.
+
+If @var{x1} is not finite, then @var{x2} must be a finite nonzero real
+with the same sign as @var{x1}; in which case @code{limit} returns:
+
+@code{(limit (lambda (x) (proc (/ x))) 0.0 (/ @var{x2}) @var{k})}
+
+@code{Limit} examines the magnitudes of the differences between
+successive values returned by @var{proc} called with a succession of
+numbers from @var{x1}+@var{x2}/@var{k} to @var{x1}.
+
+If the magnitudes of differences are monotonically decreasing, then
+then the limit is extrapolated from the degree n polynomial passing
+through the samples returned by @var{proc}.
+
+If the magnitudes of differences are increasing as fast or faster than
+a hyperbola matching at @var{x1}+@var{x2}, then a real infinity with
+sign the same as the differences is returned.
+
+If the magnitudes of differences are increasing more slowly than the
+hyperbola matching at @var{x1}+@var{x2}, then the limit is
+extrapolated from the quadratic passing through the three samples
+closest to @var{x1}.
+
+If the magnitudes of differences are not monotonic or are not
+completely within one of the above categories, then #f is returned.

+Clauses of this form have the following semantics: @r{<generator>} is
+evaluated. It may return arbitrarily many values. @r{<Guard>} is
+applied to an argument list containing the values in order that
+@r{<generator>} returned. If @r{<guard>} returns a true value for
+that argument list, @r{<receiver>} is applied with an equivalent
+argument list. If @r{<guard>} returns a false value, however, the
+clause is abandoned and the next one is tried.
+@end quotation
+
+The last @r{<clause>} may be
