    initial v1  
    44> I had a brief go at implementing local declaration splices but soon realized that implementing this involves quite a bit of replumbing. The splices would have to break up mutually-recursive groups within class, instance, and `let` declarations, and that would require changes to several bits of HsSyn. So, I settled for just fixing the panic and waiting for someone to scream loudly that they need this feature.

    6 Hello goldfire,
     6goldfire,

    88I've just run into the situation where I hoped `Q [Dec]` would have worked in a let binding, and it did not. I don't yet intend to scream, however, I am curious; Is there any Trac ticket in particular I could subscribe to, where I can follow any potential development on the implementation for supporting declaration splices in let bindings?
