it seems like a good question for committee ;) This is a forwarded message From: Doug McIlroy <doug@cs.dartmouth.edu> To: haskell@haskell.org Date: Thursday, February 09, 2006, 11:17:36 PM Subject: [Haskell] context rules for "default" ===8<==============Original message text=============== What is the rationale for the requirement that, in order for the ambiguous type of a numeric constant to be resolved by the default declaration, all classes in the context must be in the Standard Prelude or Standard Library (Revised Report 4.3.4)? This makes it hard to introduce new polymorphic functions whose domain includes the integers.
