--- | The core parser type. This is parameterised over the types @i@
--- of string being processed and @t@ of internal state representation.
---
--- This type is an instance of the following classes:
---
--- * 'Monad', where 'fail' throws an exception (i.e. fails) with an
--- error message.
---
--- * 'Functor' and 'Applicative', which follow the usual definitions.
---
--- * 'MonadPlus', where 'mzero' fails (with no error message) and
--- 'mplus' executes the right-hand parser if the left-hand one
--- fails. When the parser on the right executes, the input is reset
--- to the same state as the parser on the left started with. (In
--- other words, attoparsec is a backtracking parser that supports
--- arbitrary lookahead.)
---
--- * 'Alternative', which follows 'MonadPlus'.
