Summary: Library of safe (exception free) functions
Description:
A library wrapping @Prelude@/@Data.List@ functions that can throw
exceptions, such as @head@ and @!!@. Each unsafe function has up to four
variants, e.g. with @tail@:
* @tail :: [a] -> [a]@, raises an error on @tail []@.
* @tailMay :: [a] -> /Maybe/ [a]@, turns errors into @Nothing@.
* @tailDef :: /[a]/ -> [a] -> [a]@, takes a default to return on errors.
* @tailNote :: /String/ -> [a] -> [a]@, takes an extra argument which
supplements the error message.
* @tailSafe :: [a] -> [a]@, returns some sensible default if possible, @[]@
in the case of @tail@.
This package is divided into three modules:
* "Safe" contains safe variants of @Prelude@ and @Data.List@ functions.
* "Safe.Foldable" contains safe variants of @Foldable@ functions.
* "Safe.Exact" creates crashing versions of functions like @zip@ (errors if
the lists are not equal) and @take@ (errors if there are not enough
elements), then wraps them to provide safe variants.
