Relatedly, how would one set attributes on a variable declared in a calling function? 'readonly' and 'export' can do it for their respective attributes, but otherwise, I think you just can't.
You can't (you might be able to using nameref tricks I'm not motivated
enough to investigate); that's a consequence of dynamic scoping and
how `declare' works.
`readonly' and `export' just act on variables found using the usual
dynamic scooping rules. You could write loadable builtins `array',
`assoc', and `integer' to do the same for those attributes if you
desired.
