This is a proposal to replace the current exception mechanism in the base library with extensible exceptions.
extensible exceptions, records and syntax are my favorite missing-in-haskell-garden pets, so my +1000 syntax to defining new exceptions is a bit too fat, but it's probably impossible to use something more direct and consistent like it's done in OOP languages? also, are your examples cover all the possible scenarios of using exceptions? you may consider it as tutorial on "New Exceptions" :) is it planned to be included in 6.10? how it will work with legacy code, in particular libraries developed with old base in mind? how mixed code (throwing/catching exceptions in old and new styles) will work together? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
