Improved space consumers for megaparsec

This package provides an alternative approach for white space consuming to Text.Megaparsec.Char.Lexer.

WARNING this package is under implementation. Bugs are very likely here. All behavior is instable, don't rely on any version policy.

Available features

At the moment Text.Megaparsec.Char.Lexer.New provides combinators mostly like standard megaparsec lexer does with the following differences:

• there is a special newtype for line space consumers and a type synonym for the space and eols consumers
• indentBlock replaced by a more flexible block and headedBlock combinators
• lineFold behavior changed

In general, new approach impose more restrictions on how white space should be consumed. In my experience not enough clear rules leads here to bugs so I'd like to restrict them. However, I don't think current implementation to be the only right, so I'd like to consider any other proposals and maybe change the lib's behavior.

Usage

Just import Text.Megaparsec.Char.Lexer.New instead of Text.Megaparsec.Char.Lexer --- all you need is exported from there.
