Hi,
It would be cool if ghci debugger could grab not only the free variables in the selected expression but in one case a bit more. The case is when we stop at a function definition the first time (when just entering it).
The problem is that functions can be defined with multiple equations, each giving different names for the arguments. e.g. in
f x 0 = x f 0 x = x
when we stop at f, what do you want to see?
Right, I did not realize this problem. But your idea of using _arx<N> naming in case of more equations seems best to me. I would still like to have it available.
Even in one equation, pattern match can make it undesirable. Say, in fromJust (Just x) = ... doesn't allow you access to the argument directly. Can _argN be provided in *all* cases (possibly in addition to other bindings)? -Isaac
