#77: Binding variables on the prompt -------------------------------------------------+-------------------------- Reporter: apfelmus | Owner: nobody Type: enhancement | Status: new Priority: major | Milestone: Component: hugs | Version: current Keywords: interactive prompt variable binding | -------------------------------------------------+-------------------------- In GHCi, it's possible to bind variables at the interactive prompt, like {{{

let x = 1 x + 1 2 y <- readFile "Foo.bar" "Hello World" length y 11 }}}

The rule is that the bindings are legal in the do-notation for the IO- monad. For details, see [http://www.haskell.org/ghc/docs/latest/html/users_guide/ch03s04.html Interactive evaluation at the prompt] in the GHC user's guide. I'm dearly missing this feature in Hugs! -- Ticket URL: http://hackage.haskell.org/trac/hugs/ticket/77 Hugs http://www.haskell.org/hugs/ Hugs 98, an interpreter for Haskell
