runParseResult will still result in Nothing, if there are recorded errors.
Add a warning. This doesn't fail the parsing process.
Add multiple warnings at once.
Add an error, but not fail the parser yet.
For fatal failure use parseFatalFailure
Add an fatal error.
A mzero.
Get cabal spec version.
Set cabal spec version.
Forget ParseResults warnings.
Chain parsing operations that involve IO actions.
