Hey Chet: why doesn't bash accept non-compound commands as functions? I have
wondered. Apparently other shells disagree on this...?
Because the POSIX grammar says a function body is a compound command,
optionally followed by a redirection list, and I never saw the need to
extend that.
function_definition : fname '(' ')' linebreak function_body
;
function_body : compound_command /* Apply rule 9 */
| compound_command redirect_list /* Apply rule 9 */
;
