tcreate ~f create a new eager parser state. f will be called on each s-expression found. If f raises, then the parser is made unusable (stop t is invoked).
no_sexp_is_error controls the behavior of the parse when the end of input is reached and no s-expression has been found. When no_sexp_is_error is false (the default) feed_eoi just returns (), when it is false feed_eoi raises. In any case, if the end of input is reached while parsing an incomplete s-expression such as (abc, error is raised.
f must not save the read-only parser state it receives to access it after returning. It is unspecified what values it will read if it does so.
