Text.LambdaOptions.List

Description

List newtype wrapper that can be pattern matched against for parsing.

Synopsis

newtype List a = List {
- unList :: [a]
}

Documentation

newtype List a Source #

A simple wrapper over [a]. Used to avoid overlapping instances for Parseable [a] and Parseable String.

Constructors

List
Fields unList :: [a]
