Make it possible to purely use the parser
It is claimed that the parser is pure but one of the arguments is DynFlags
. The only safe way to construct a copy of DynFlags
requires IO so it is not possible to use the parser purely.
I propose to introduce a new datatype ParserOptions
which contains the options used by the parser and a function DynFlags -> ParserOptions
so that it is possible to purely construct a ParserOptions
and use the parser purely. This would be useful for external users of the parser.
