Doubt about funs

[Chandrashekhar Mullaparthi]

IMHO, adding the arity in the fun specification will not add any more value.
On the contrary, it'll be a bit of a pain when we want to write code like:

somefunc(Fun) ->
  receive
    Pattern1 -> Fun(a,b);
    Pattern2 -> Fun(a,b,c)
  end.

cheers,
Chandru
