from man bash, to define a function use;

so why do I get a syntax error for
function good_dir [[ -n $1&& -d $1&& -r $1&& -x $1 ]]
bash: syntax error near unexpected token `[['
I see this in bash(1):
SHELL GRAMMAR

Shell Function Definitions
...
[ function ] name () compound-command [redirection]
and do not see the version you show without the parens.
It's there. Look at the 3rd sentence:
"If the function reserved word is supplied, the parentheses are
