Re: Proposal #3339: Add (+>) as a synonym for mappend

That was discussed previously (also in the ticket). Using infixl would cause performance problems with, e.g., lists and other list-like structures such as things that translate to CPS. On 6 November 2011 17:40, Malcolm Wallace wrote:

This is a call for consensus. Do we agree to add

   infixr 6 <>

   (<>) :: Monoid m => m -> m -> m    (<>) = mappend

Currently Text.Pretty declares infixl 5 <>, <+>.

So what is the rationale for the new Monoidal operator <> to be declared infixr 6?  Why can it not simply preserve the same fixity as already used by Pretty's <> ?
