Re: constants and functions without arguments

Hi,

I hope this is the right forum to post my question to.

Given a lazy pure functional language do we need to differntiate (in syntax) between constants and functions without agruments? And if we don't need to, does Haskell make a difference?

From a pedantic point of view your question makes no sense. The definition of a function is something that takes an argument and transforms it to a result. So a function always has exactly one argument. Period.

But from a practical point of view, yes you can regard constants as functions with no arguments. And it makes sense from a syntactic point of view: f0 = e0 f1 x = e1 f2 x y = e2 f3 x y z = e3 ... -- Lennart
