Hello, (and sorry for the preceding accidental empty message),
I'd like to ask a question concerning a following passage in "Yet another Haskell Tutorial" that ushers in the topic of monads: <<After all, suppose you have a function that reads a string from the keyboard. Ifyou call this function twice, and the user types something the first time and something else the second time, then you no longer have a function, since it would return two different values.>> How do I have to interpret this? I cannot make sense of it for I do not see where the definition of a function that I know is violated. I view it that way: The string is just a kind of argument to the string-reading function and that different strings (i.e. different arguments) yield different return values is a commonplace phenomenon with functions, isn't it? How do I have to alter this (over?)simple interpretation to see the point the author wants to make? Thank you very much in advance. Christian -- Echte DSL-Flatrate dauerhaft für 0,- Euro*.
