How about adding a string[string] or a variant[string] to the Exception

For instance:

catch (Exception ex) {
if ("transient" in ex.details) {
repeatOneMoreTime();
}
if ("i18n_code" in ex.details) {
log(translate(ex.details["i18n_code"]));
}
}
...
Details can be standard by convention or otherwise custom.
(I can see that this can lead to messy proliferation of details, but at
least solves most of the issues).
How would you know which keys are available in "ex.details", documentation?
Programmatically, too. A string templating engine would take the table
and format it for the appropriate language.
