New type of ($) operator in GHC 8.0 is problematic

[Takenobu Tani]

Hi,

I know the issue of beginner's Prelude.


But how about "profile"? (like H264/MPEG4-AVC profile [1])

  * Beginner Profile     : beginner's Prelude or ghci beginner's
representation mode

  * Main Profile         : Haskell 2010 standard

  * Leading edge Profile : set of GHC extensions


If beginners know exist of profile at first, they may avoid to confuse by
step-up?
More confused?

Already we implicitly have at least two profiles (Haskell2010 and GHC
extensions).

Regards,
Takenobu
