Re: [Haskell-cafe] explicit annotations on kind polymorphism for data types
Correct. I just meant that you can use a lowercase x or a lowercase chi (χ). Any lowercase characters (as defined by Unicode) can be used as identifiers. -Brent On Thu, Aug 23, 2012 at 11:09:41AM -0400, dude wrote: Not in 7.4.2, correct? -- dude On 08/22/2012 09:58 AM, Brent Yorgey wrote: I believe in the paper it is actually a lowercase Greek chi (χ), which should work too. ;) -Brent On Wed, Aug 22, 2012 at 08:15:48AM +0200, José Pedro Magalhães wrote: Nope, but it should work on 7.6 (also on the release candidate).

Nope, but it should work on 7.6 (also on the release candidate). The 'X' should be lowercase, though, like type variables.

I believe in the paper it is actually a lowercase Greek chi (χ), which should work too. ;) -Brent On Wed, Aug 22, 2012 at 08:15:48AM +0200, José Pedro Magalhães wrote: Nope, but it should work on 7.6 (also on the release candidate).
