11	Fixities aren't handled during parsing	nibro	nibro	"Currently, operator expressions are parsed as left-associative, and of the same fixity. It would be nice to have the parser able to return a syntax tree where the fixity is taken into account correctly.

There are several issues involved:

 * Have the parser take a set of known fixities, and take them into account when parsing.
 * Have the parser react to (possibly infix) fixity declarations in the module it is parsing.
 * Possibly handle operators with unknown fixity in a different way - though the H98 report stipulates a default behavior, so I believe it would be best to follow that.

Neil Mitchell's HLint has code to massage the AST given a set of known fixities. I will use that as my starting point."	feature request	closed	critical	Full code support	parser		fixed
