[Haskell-cafe] create a type for selecting functions already in the module

[Oterman-Fernandez, Ana-Maria]

Hi!

I have implemented a module with some functions and now I would like to create a type for selecting between this functions:

For example: if f1, f2,...fn are the names of the functions in the module, I need to do something like this:

data Consult = f1 | f2 |....| fn  

for applying them whenever the user wants.

but by this way is not possible.

Do you know how can I do this? Thank you!

Ana Maria
