Given the definition of a Haskell function, Haskell is a pure language.
The notion of a function in other languages is not:
int randomNumber();
The result of this function is an integer. You can't replace the
function call by its result without changing the meaning of the program.
I'm not sure this is fair. It's perfectly okay to replace a call
"randomNumber()" by that method's *body* (1), which is what you argue is
okay in Haskell.
Martijn.
(1) Modulo some renaming, and modulo the complicated non-compositional
meanings of control statements such as "return", etc.
