Yes, please. For suppression of word splitting, maybe something like
the following would work?
%token Export Readonly
/* 'export' 'readonly' */
simple_command : cmd_prefix cmd_word cmd_suffix
| cmd_prefix cmd_word
| cmd_prefix
| assign_cmd_name assign_cmd_suffix
| assign_cmd_name
| cmd_name cmd_suffix
| cmd_name
;
assign_cmd_name : Export
| Readonly
;
assign_cmd_suffix : io_redirect
| assign_cmd_suffix io_redirect
| ASSIGNMENT_WORD
| assign_cmd_suffix ASSIGNMENT_WORD
| WORD /* Apply rule 7b */
| assign_cmd_suffix WORD /* Apply rule 7b
;
Side-effects: export and readonly would become keywords that can be
quoted away. export and readonly with cmd_prefix would be ill-formed.
\export foo=bar; # look for 'export' command on $PATH
foo=bar export; # syntax error
