Thanks Daniel, that's very simple! Realizing this in TH seems be impossible, is it right? On Wed, Mar 27, 2013 at 10:33 PM, Daniel Trstenjak < daniel.trstenjak@gmail.com> wrote:
Hi Corentin,

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...
You can even use cpp to get something like:
#define CALL(func) call (func) #func
CALL(\a -> a + 1) => call (\a -> a + 1) "\a -> a + 1"
Greetings, Daniel
