use different types for key/value. for example, use word! for key, string! for value. this works often, like i have file! as key and numbers (position etc) as values, or simple types as keys and blocks as values etc. 'find checks for type, so find somewhere 'find-me find somewhere "find-me" are different.

i use this: now-is: function [ "change value after key, if it is present, otherwise append both" series key value] [here] [ here: find series key either here [change/only next here value] [append series reduce [key value]] ]
