@techtangents @kaleidic a "function" writes global mutable state; never reads, remains merilly memoizable: referencially transparent?

@dibblego@techtangents@kaleidic that was my point! Hence "function" quoted. Code writing global state can be referentially transparent

@dibblego@techtangents@kaleidic int A=0; int I(x) {A=x; return x+1}. Reads no global state, yet writes. I(y) always returns same result -
@malk_zameth@techtangents@kaleidic aha! No it doesn't return the same result. I agree RT is insufficient though (is a consequence). - Show replies
