"A program that has no side effects whatsoever is a kind of black box. All you can tell is that the box gets hotter."

@darinmorrison Those who believe they program with *exclusively* functions are working with a different definition of "program" than I am.

@djspiewak @darinmorrison Many of us program exclusively with functions are you know them. Come join us.

@dibblego @darinmorrison The quote uses a particular definition of "program" which I believed to be widely held. Apparently it isn't.

@djspiewak @darinmorrison there is no definition where the quote makes any sense at all. It is held by no single person.

@dibblego @darinmorrison Clearly it’s not held by “no single person” since I hold the definition as well as SPJ.

@djspiewak @darinmorrison it is far more likely that you have misunderstood than SPJ saying something so obviously wrong.

@dibblego @darinmorrison My quote is a *trivial* derivation from what he said, taking a “function” to always be a “pure function” (by defn).
