Documentation
lookup1 :: Eq k => k -> AssocList k [e] -> [e] Source #
lookup with empty list (empty string) as default value
addEntry :: Eq k => k -> v -> AssocList k v -> AssocList k v Source #
add an entry, remove an existing entry before adding the new one at the top of the list, addEntry is strict
