From the article:
but you can also write pure functions in C, for example:
int f(int x) {
int y = 0;
int z = 0;
y = 2 * x;
z = y + 1;
return z / 3;
}
You can do the same with assembly language too. Pure functions
don’t just belong to purely functional languages. You can write
pure functions in any language, but the important thing is, you
should be allowed to use side-effects too.
Do you want to inform that author about the purity in D? :-)
