[Haskell-cafe] Remove redundancy with Template Haskell

[Corentin Dupont]

Hi Café,
I have a function that looks like this:
call :: SomeFunction -> String -> SomeState

The string is actually the representation of the function passed in
parameter. It is stored in the state for documentation.
So a call looks like that:
call (\a -> putStrLn a)   "\a -> putStrLn a"

There is a clear redundancy here, how could I remove it with Template
Haskell?
I cannot figure out...

Thanks!
Corentin
