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

@malk_zameth @techtangents @kaleidic Not a function, therefore not even no.

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

@malk_zameth @techtangents @kaleidic how can it be so?

@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
