updateAppend :: (a -> Bool) -> a -> (a -> a) -> [a] -> [a] Source #
Needs break from utility-ht in order to be as lazy as updateAppend'.
updateAppend' :: (a -> Bool) -> a -> (a -> a) -> [a] -> [a] Source #
Apply f to the first element, where p holds.
If no such element exists, append the default value deflt to the list.
