Hi,
Yet a cleaner solution would be to make the init function to return
the map to assign to the global variable, so there is no hidden
dependency:
declare variable $global-map := my:init();
declare function my:init() {
let $map := map:map()
...
return
$map
};
If the init code is that simple, the let expression can then even be
used straight in the variable value expression, without using a
function.
Avoiding side-effects when none is required will save you some
(hard-to-track-down) troubles.
Regards,
