Use keywords, not ordinary symbols, in the structure syntax for hash tables. lisp/ChangeLog addition: 2010-01-09 Aidan Kehoe <kehoea@parhasard.net> * descr-text.el (describe-char-unihan-field-descriptions): * cl-macs.el: Use keywords, not ordinary symbols, in the hash table read syntax, for compatibility with Common Lisp and recent GNU Emacs. man/ChangeLog addition: 2010-01-09 Aidan Kehoe <kehoea@parhasard.net> * lispref/objects.texi (Hash Table Type): * lispref/hash-tables.texi (Introduction to Hash Tables): Use keywords, not ordinary symbols, in the hash table read syntax; document that we do accept the ordinary symbols for the sake of backward-compatiblity. 2010-01-09 Aidan Kehoe <kehoea@parhasard.net> * elhash.c: (print_hash_table, print_hash_table_data) (hash_table_instantiate) (structure_type_create_hash_table_structure_name): (syms_of_elhash): Use keywords, not ordinary symbols, in the hash table read syntax, for compatibility with Common Lisp and recent GNU Emacs. Accept the non-keyword syntax, but don't allow mixing of the two styles.
