#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!
