LazyByteString.hs

{-|
Simple 'Applicative' parser whose input is lazy 'ByteString'.
The usage is the same as parsec.

Parsec 3 provides features which Parsec 2 does not provide:

* 'Applicative' style

* 'ByteString' as input

But Haskell Platform includes Parsec 2, not Parsec 3. Installing
Parsec 3 to Haskell Platform environment makes it mess. So, this library
was implemented.
