Revise print_symbol(), never calling is{float,ratio}_string(). src/ChangeLog addition: 2015-05-08 Aidan Kehoe <kehoea@parhasard.net> * print.c (print_symbol): Revise this. No longer call isfloat_string() and isratio_string() on practically every symbol seen; check explicitly for the known float format in this function, which turns out to be a more limited and cheap job than you would think. Also check for integer and ratio syntax in passing. Use Vdigit_fixnum_map when working out whether a given character is a digit. * lisp.h: Make Vdigit_fixnum_map available generally. tests/ChangeLog addition: 2015-05-08 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-reader-tests.el: Check read and print handling of symbols that look like numbers. In passing, check the read and print handling of the associated numbers.

(defun define-widget (name class doc &rest args)
  "Define a new widget type named NAME from CLASS.

NAME and CLASS should both be symbols, CLASS should be one of the
existing widget types, or nil to create the widget from scratch.

After the new widget has been defined, the following two calls will
create identical widgets:

* (widget-create NAME)

* (apply 'widget-create CLASS ARGS)

The third argument DOC is a documentation string for the widget."
  (check-argument-type 'symbolp name)
  (check-argument-type 'symbolp class)

  (put name 'widget-documentation doc)
