Hi,
Well I've searched the OTP book, trawled the erlang questions archive(very good by the way, however
there should
be an all button on the Available Subdirectories) and I still can't work out how to do it.

How do you extract the arity of a Fun? e.g How do I do this

F = fun(X,Y,Z) -> end,

X = get_fun_arity(F).

3

All the best

Tony
