characters from a scanner in bulk. The function @<func> is invoked
repeatedly, as if by
\begin{prog}
- (multiple-value-bind (@<donep> @<used>) \\ \ind\ind
- (funcall @<func> @<buf> @<start> @<end>) \- \\

The argument @<buf> is a simple string; @<start> and @<end> are two
fails: the @<fail> function is called with no arguments, and is expected to
return two values. If omitted, @<fail> defaults to
\begin{prog}
- (lambda () \\ \ind
