DICTIONARY dict_union(DICTIONARY dict1, DICTIONARY dict2)
This function merges the two dictionaries by adding each association from dict2 into dict1. In the case of conflicts, the values in dict2 take precedence. Example:
dict_union(#[["foo", 1], ['baz, 3]], #[["foo", 2], ["bar", 2]])
=> #[["foo", 2], ['baz, 3], ["bar", 2]]
